Closes#5449
A file containing the string "vim" followed by a very large number in a modeline
location will trigger an overflow in getdigits() which is called by
chk_modeline() when trying to parse the version number.
Add getdigits_safe(), which does not assert overflows, but reports them to the
caller.

Problem: Setting 'display' to "lastline" is a drastic change, while
omitting it results in lots of "@" lines.
Solution: Add "truncate" to show "@@@" for a truncated line.

In Vim,
:echo system('cat - &', 'foo')
works because for both system() and :! Vim writes input to a temp file and uses
shell syntax to redirect the file to the backgrounded `cat` (get_cmd_output()
.. make_filter_cmd()).
In Nvim,
:echo system('cat - &', 'foo')
fails because we write the input directly via pipes (shell.c:do_os_system()),
but (per POSIX[1]) backgrounded process input stream is redirected from
/dev/null (unless overridden by shell redirection; supported only by some shells
[2]), so our writes are ignored, the process exits quickly, and if we are
writing data larger than the buffer size we'll see EPIPE.
This still works:
:%w !tee > foo1358.txt &
but this does not:
:%w !tee foo1358.txt &
though it *should* (why doesn't it?) because we still do the temp file dance
in do_bang() .. do_filter().

These tests are essentially affirming a regression vs Vim. In Vim,
:echo system('cat - &', 'foo')
returns "foo", because Vim internally wraps the command with shell-specific
syntax to redirect the streams from /dev/null[1].
That can't work in Nvim because we use pipes directly (instead of temp files)
and don't wrap the command with shell-specific redirection syntax.

Problem: Cannot use a window ID where a window number is expected.
Solution: Add LOWEST_WIN_ID, so that the window ID can be used where a
number is expected.

Problem: Although emoji characters are ambiguous width, best is to treat
them as full width.
Solution: Update the Unicode character tables. Add the 'emoji' options.

`deprecated.txt` is a place for deprecated tags to live.
- Encourages aggressive documentation of deprecations without cluttering
the main help files.
- Provides a single browsable reference of all deprecations.
Other changes:
- Move tags to doc/vim_diff.txt.
- Remove doc/quotes.txt. It has little historical value, except maybe the
Larry Wall quote.
- fix synopsis highlighting in other locales. Cannot always rely on the first
line for the section in some locales; instead, use the file path and
explicitly set b:man_sect to the actual section.
- eliminate separate s:man_args function
- simplify logic: do not reuse buffer content
- introduce b:man_default_sects Fixes#5233
- introduce <Plug>(man_vsplit), <Plug>(man_tab)
- simplify regexps
To healthcheck the "foo" plugin:
:CheckHealth foo
To healthcheck the "foo" and "bar" plugins:
:CheckHealth foo bar
To run all auto-discovered healthchecks:
:CheckHealth
- Use execute() instead of redir
- Fixed logic on suboptimal pyenv/virtualenv checks.
- Move system calls from strings to lists. Fixes#5218
- Add highlighting
- Automatically discover health checkers
- Add tests

- Links to Search by default
screen.c: Combine CursorLine with QuickFixLine
- HLF_QFL takes priority over HLF_CUL
docs: Updated to mention QuickFixLine
runtime: Added QuickFixLine to nvimHLGroup
tests: QuickFixLine highlight
- Weird tab+space combination used for alignment. All spaces now
- Added back <C-T> mapping (somehow we missed that completely)
- Fixed mistake that <Plug>(Man) opens in a new tab. Also added note at
top on how the window is chosen/opened.
- Clarified q local mapping
- Removed section that shows an example autocmd to add desired folding
style.
- Removed random line in `usr_12.txt` about `<Leader>` and backslash.
- :Man supports completion, not auto-completion.
Closes#5171
In 3b12bb225a, ":oldfiles" was taught to
behave like Vim's ":browse oldfiles" if ":oldfiles!" was used. However,
this conflates the use of ! for abandoning a modified buffer with
choosing one file out of a list of oldfiles.
Now that ":browse" is supported again, ":browse oldfiles" will allow the
user to select an old file, while still complaining if that would cause
a modified buffer to be abandoned. ":browse oldfiles!" will just
abandon the buffer, as expected.
