Regarding the individual items in the header:
`Vim - Vi improved by Bram Moolenar`
Bram Moolenar is already mentioned throughout the documentation, as
well as the intro screen.
`:help uganda`
It's already shown to all users who don't use `shortmess+=I` upon
starting nvim, and is already placed prominently in help.txt, i.e.,
`:help` run with no arguments.
`:help credits`
Already mentioned near the top of help.txt.
`README.md`
Already mentioned in develop.txt.
In Windows we can't assume errno will be set by calls to os_* functions,
instead the return value from os_* functions can be used. This commit fixes two
occurences for os_open().
1. EFBIG is replaced with UV_EFBIG and checked against the return from os_open().
2. EOVERFLOW does not have a corresponding libuv constant, and is not defined
by open() in Windows - disabled this case with a UNIX guard, and check the return
value against -EOVERFLOW (libuv errors are negative errno values in Unix).
Previously os_getperms() returned -1 for any error condition, it
now returns the libuv error code (as returned by os_stat()). This
allows checking for error conditions without relying on errno
(which not available in Windows).
The only case where the errno value from os_getperms() was being used
was in readfile() to set the new-file flag - replaced the errno check
with UV_ENOENT.
Problem: On some systems automatically adding the missing EOL causes
problems. Setting 'binary' has too many side effects.
Solution: Add the 'fixeol' option, default on. (Pavel Samarkin)

What works:
1. ShaDa file dumping: header, registers, jump list, history, search patterns,
substitute strings, variables.
2. ShaDa file reading: registers, global marks, variables.
Most was not tested.
TODO:
1. Merging.
2. Reading history, local marks, jump and buffer lists.
3. Documentation update.
4. Converting some data from &encoding.
5. Safer variant of dumping viminfo (dump to temporary file then rename).
6. Removing old viminfo code (currently masked with `#if 0` in a ShaDa file for
reference).
Problem: Accessing memory before an allocated block.
Solution: Check for not going before the start of a pattern. (Dominique Pelle)

os_file_is_readonly() in its current form is equivalent to
!os_file_is_writable(). This does not appear to be a bug, because Vim's
use of check_file_readonly() (which we changed to os_file_is_readonly())
is equivalent to !os_file_is_writable() in every case.
os_file_is_readonly() also fails this test:
returns false if the file is non-read, non-write
A more useful form would define behavior under these cases:
- path is executable (but not writable)
- path is non-existent
- path is directory
But there is no reason for os_file_is_readonly() to exist, so remove it.
Problem: FEAT_OSFILETYPE is used even though it's never defined.
Solution: Remove the code. (Christian Brabandt)

Not applicable, this code has already been removed in Neovim. Included
some of the style tweaks.
Problem: When using Insert mode completion combined with autocommands the
redo command may not work.
Solution: Do not save the redo buffer when executing autocommands. (Yasuhiro
Matsumoto)

We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
- Remove JobActivity autocmd and v:job_data variable
- Simplify `jobstart` to receive:
- An argument vector
- An optional dictionary which may contain any of the current `jobstart`
options plus `on_stdout`, `on_stderr` and `on_exit` callbacks.
- Refactor and add more job tests
- Update documentation
This commit integrates libvterm with Neovim and implements a terminal emulator
with nvim buffers as the display mechanism. Terminal buffers can be created
using any of the following methods:
- Opening a file with name following the "term://[${cwd}//[${pid}:]]${cmd}"
URI pattern where:
- cwd is the working directory of the process
- pid is the process id. This is just for use in session files where a pid
would have been assigned to the saved buffer title.
- cmd is the command to run
- Invoking the `:terminal` ex command
- Invoking the `termopen` function which returns a job id for automating the
terminal window.
Some extra changes were also implemented to adapt with terminal buffers. Here's
an overview:
- The `main` function now sets a BufReadCmd autocmd to intercept the term:// URI
and spawn the terminal buffer instead of reading the file.
- terminal buffers behave as if the following local buffer options were set:
- `nomodifiable`
- `swapfile`
- `undolevels=-1`
- `bufhidden=hide`
- All commands that delete buffers(`:bun`, `:bd` and `:bw`) behave the same for
terminal buffers, but only work when bang is passed(eg: `:bwipeout!`)
- A new "terminal" mode was added. A consequence is that a new set of mapping
commands were implemented with the "t" prefix(tmap, tunmap, tnoremap...)
- The `edit` function(which enters insert mode) will actually enter terminal
mode if the current buffer is a terminal
- The `put` operator was adapted to send data to the terminal instead of
modifying the buffer directly.
- A window being resized will also trigger a terminal resize if the window
displays the terminal.
Problem : String not null terminated @ 1543.
Diagnostic : Real issue.
Rationale : We are reading a struct block0, which contains some string
fields, from a file, without checking for string fields to
be correctly terminated. That could cause a buffer overrun
if file has somehow been garbled.
Resolution : Add string fields check for nul termination.
Mark issue as intentional (there seems to be no way of
teaching coverity about read_eintr being ok that way).

- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code
- Remove abstract_ui global, now it is always active
- Remove some terminal handling code
- Remove unused functions
- Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs
- Remove tgetent/terminfo from version.c
- Remove curses/terminfo dependencies
- Only start/stop termcap when starting/exiting the program
- msg_use_printf will return true if there are no attached UIs(
messages will be written to stdout)
- Remove `ex_winpos`(implement `:winpos` with `ex_ni`)
Problem : Out-of-bounds access @ 5815.
Diagnostic : False positive.
Rationale : Error occurs when event_name2nr() returns NUM_EVENTS, which
means an event with that name was not found. That cannot
happen, as previous check using find_end_event() @ 5744
ensures event name exists.
Resolution : Assert event_name2nr() result is less thatn NUM_EVENTS.
Regarding dict_lookup() in eval.c: both definitions are the same, the
only difference being the spacing between the indirection operator and
the indentation level.
