Before this PR, the behavior of nvim_paste is:
- When vim.paste() returns false, return false to the client, but treat
following chunks normally (i.e. rely on the client cancelling the
paste as expected).
- When vim.paste() throws an error, still return true to the client, but
drain the following chunks in the stream without calling vim.paste().
There are two problems with such behavior:
- When vim.paste() errors, the client is still supposed to send the
remaining chunks of the stream, even though they do nothing.
- Having different code paths for two uncommon but similar situations
complicates maintenance.
This PR makes both the cancel case and the error case return false to
the client and drain the remaining chunks of the stream, which, apart
from sharing the same code path, is beneficial whether the client checks
the return value of nvim_paste or not:
- If the client checks the return value, it can avoid sending the
following chunks needlessly after an error.
- If the client doesn't check the return value, chunks following a
cancelled chunk won't be pasted on the server regardless, which leads
to less confusing behavior.
In the api_info() output:
:new|put =map(filter(api_info().functions, '!has_key(v:val,''deprecated_since'')'), 'v:val')
...
{'return_type': 'ArrayOf(Integer, 2)', 'name': 'nvim_win_get_position', 'method': v:true, 'parameters': [['Window', 'window']], 'since': 1}
The `ArrayOf(Integer, 2)` return type didn't break clients when we added
it, which is evidence that clients don't use the `return_type` field,
thus renaming Dictionary => Dict in api_info() is not (in practice)
a breaking change.
Problem: Wrong breakindentopt=list:-1 with multibyte chars or TABs in
text matched by 'formatlistpat' (John M Devin)
Solution: Use the width of the match text (zeertzjq)
fixes: vim/vim#15634closes: vim/vim#1563561a6ac4d00
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: Contents of terminal buffer are not reflown when Nvim is
resized.
Solution: Enable reflow in libvterm by default. Now that libvterm is
vendored, also fix "TUI rapid resize" test failures there.
Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.
According to :h win32-PATH, "the same directory as Vim" means the same
directory as the Vim executable, not Vim's current directory. In patch
8.2.4860 these two concepts were mixed up.

Problem: No way to get the arity of a Vim function

Problem: Unused assignment in sign_define_cmd()
Solution: Remove the assignment. Also document the "priority" flag of
sign_define(). (zeertzjq)
closes: vim/vim#15169fc3f5dba52
Problem: not possible to assign priority when defining a sign
(Mathias Fußenegger)
Solution: Add the priority argument for the :sign-define ex command and
the sign_define() function (LemonBoy)
Use the specified value instead of the default one (SIGN_DEF_PRIO) when
no priority is explicitly specified in sign_place or :sign place.

Problem: signed number detection for CTRL-X/A can be improved
(Chris Patuzzo)
Solution: Add the new "blank" value for the 'nrformat' setting. This
will make Vim assume a signed number only if there is a blank
in front of the sign.

This is a breaking change which will make refactor of typval and shada
code a lot easier. In particular, code that would use or check for
v:msgpack_types.binary in the wild would be broken. This appears to be
rarely used in existing plugins.
Also some cases where v:msgpack_type.string would be used to represent a
binary string of "string" type, we use a BLOB instead, which is
vimscripts native type for binary blobs, and already was used for BIN
formats when necessary.
msgpackdump(msgpackparse(data)) no longer preserves the distinction
of BIN and STR strings. This is very common behavior for
language-specific msgpack bindings. Nvim uses msgpack as a tool to
serialize its data. Nvim is not a tool to bit-perfectly manipulate
arbitrary msgpack data out in the wild.
The changed tests should indicate how behavior changes in various edge
cases.
Problem: A custom 'statuscolumn' needs to check a bunch of options and
placed signs to replicate the default number column.
Solution: Rework %l item to include the necessary logic to mimic the
default number column. Remove now redundant %r item.
Problem: the previous documentation falsely states that "v" always
refers to the start of a visual area. In fact, the reference of "v" and
"." complement each other. If the cursor is at the start of
a (characterwise) visual area, then "v" refers to the end of the area.
Solution: be more verbose and explicit about the connection between "."
and "v" and also refer to |v_o| which many vim users will be familiar
with for visual areas.
