Problem:
Cannot enter multiline prompts in a buftype=prompt buffer.
Solution:
- Support shift+enter (`<s-enter>`) to start a new line in the prompt.
- Pasting multiline text via OS paste, clipboard, "xp, etc.
- A/I in editable region works as usual.
- i/a/A/I outside of editable region moves cursor to end of current
prompt.
- Support undo/redo in prompt buffer.
- Support o/O in prompt buffer.
- Expose prompt location as `':` mark.
Problem: Screen may be updated by a msg_showcmd event before '"' is
cleared from the screen with register insertion.
Solution: Emit the msg_showcmd event before clearing the '"'.
Problem: potential buffer underflow in insertchar()
Solution: verify that end_len is larger than zero
(jinyaoguo)
When parsing the end-comment leader, end_len can be zero if
copy_option_part() writes no characters. The existing check
unconditionally accessed lead_end[end_len-1], causing potential
underflow when end_len == 0.
This change adds an end_len > 0 guard to ensure we only index lead_end
if there is at least one character.

Problem:
When doing paste operation mouse code tries to figure out it it is
dealing with a multi-line register by calling yank_register_mline(),
which fetches register data and checks its type. Later the code calls
either do_put() or insert_reg() which fetch register data again. This is
unnoticeable when working with internal neovim registers, but starts
hurting when dealing with clipboards, especially remote one (forwarded X
or socket tunnel or similar).
Solution:
Change yank_register_mline() to also return pointer to the
register structure prepared for pasting, and insert_reg() to accept
such register pointer and use it if it is supplied. do_put() already
has support for accepting a register structure to be used for pasting.
Fixes#33493
Problem: When switching to another window or tab page while the
completion menu is active, the menu stays visible, although it
belongs to the previous window/tab page context (Evgeni
Chasnovski).
Solution: Track the window and tab page where completion started. Detect
changes in the main editing loop and cancel completion mode if
the current window or tab page differs from where completion
started.

Problem: too many strlen() calls in edit.c
Solution: refactor edit.c and remove strlen() calls
(John Marriott)
This commit attempts to make edit.c more efficient by:
- in truncate_spaces() pass in the length of the string.
- return a string_T from get_last_insert(), so that the length of the
string is available to the caller.
- refactor stuff_insert():
- replace calls to stuffReadbuff() (which calls STRLEN() on it's
string argument) with stuffReadbuffLen() (which gets the length of
it's string argument passed in).
- replace call to vim_strrchr() which searches from the start of the
string with a loop which searches from end of the string to find the
last ESC character.
- change get_last_insert_save() to call get_last_insert() to get the
last_insert string (the logic is in one place).

Problem: using global variable for get_insert()/get_lambda_name()
(after v9.1.1151)
Solution: let the functions return a string_T object instead
(Yee Cheng Chin)
In vim/vim#16720, `get_insert()` was modified to store a string length in a
global variable to be queried immediately by another `get_insert_len()`
function, which is somewhat fragile. Instead, just have the function
itself return a `string_T` object instead. Also do the same for
`get_lambda_name()` which has similar issues.

Problem: The 'preinsert' feature requires Ctrl-Y to confirm insertion,
but Ctrl-Y only works when the popup menu (pum) is displayed.
Without enforcing this dependency, it could lead to confusing
behavior or non-functional features.
Solution: Modify ins_compl_has_preinsert() to check for both 'menu' and
'menuone' flags when 'preinsert' is set. Update documentation
to clarify this requirement. This avoids adding complex
conditional behaviors. (glepnir)

Problem: When completion leader changes, text that might be reinserted
immediately after is deleted. This unnecessarily affects
extmarks. #31387 restored the original extmarks but that
prevents end_right_gravity marks from growing.
Solution: Avoid deleting leader text that will be reinserted.
Problem: Option metadata like list of valid values for an option and
option flags are not listed in the `options.lua` file and are instead
manually defined in C, which means option metadata is split between
several places.
Solution: Put metadata such as list of valid values for an option and
option flags in `options.lua`, and autogenerate the corresponding C
variables and enums.

Problem: inserting with a count is inefficient
Solution: Disable calculation of the cursor position and topline, if a
count has been used (Ken Takata)
Optimize insertion when using :normal 10000ix.
This patch optimizes the insertion with a large count (e.g. `:normal
10000ix`).
It seems that calculation of the cursor position for a long line is slow
and it takes O(n^2). Disable the calculation if not needed.
Before:
```
$ time ./vim --clean -c 'normal 10000ix' -cq!
real 0m1.879s
user 0m1.328s
sys 0m0.139s
$ time ./vim --clean -c 'normal 20000ix' -cq!

$ time ./vim --clean -c 'normal 40000ix' -cq!
real 0m23.588s
user 0m23.187s
sys 0m0.140s
```
After:
```
$ time ./vim --clean -c 'normal 10000ix' -cq!
real 0m0.187s
user 0m0.046s
sys 0m0.093s

Use the grapheme break algorithm from utf8proc to support grapheme
clusters from recent unicode versions.
Handle variant selector VS16 turning some codepoints into double-width
emoji. This means we need to use ptr2cells rather than char2cells when
possible.
Problem:
Variables are often assigned multiple places in common patterns.
Solution:
Replace these common patterns with different patterns that reduce the
number of assignments.
Use `MAX` and `MIN`:
```c
if (x < y) {
x = y;
}
// -->
x = MAX(x, y);
```
```c
if (x > y) {
x = y;
}
// -->
x = MIN(x, y);
```
Use ternary:
```c
int a;
if (cond) {
a = b;
} els {
a = c;
}
// -->
int a = cond ? b : c;
```

Problem: Left shift is incorrect with vartabstop and shiftwidth=0
Solution: make tabstop_at() function aware of shift direction
(Gary Johnson)
The problem was that with 'vartabstop' set and 'shiftwidth' equal 0,
left shifts using << were shifting the line to the wrong column. The
tabstop to the right of the first character in the line was being used
as the shift amount instead of the tabstop to the left of that first
character.
The reason was that the tabstop_at() function always returned the value
of the tabstop to the right of the given column and was not accounting
for the direction of the shift.
The solution was to make tabstop_at() aware of the direction of the
shift and to choose the tabtop accordingly.
A test was added to check this behavior and make sure it doesn't
regress.
While at it, also fix a few indentation/alignment issues.
