vim.tbl_get takes a table with subsequent string arguments (variadic) that
index into the table. If the value pointed to by the set of keys exists,
the function returns the value. If the set of keys does not exist, the
function returns nil.
On TUI startup write the CSI sequence that signals to the controlling
terminal that Neovim supports the CSI u scheme for encoding modifiers
documented in [1].
This is similar to, but distinct from, Vim's usage of the `t_TI` and
`t_TE` variables to handle Xterm's `modifyOtherKeys` setting. For a
longer explanation on those differences see [2]. Since Neovim uses
libtermkey for key input handling, we use the CSI u encoding rather than
Xterm's modifyOtherKeys encoding.

vim-patch:8.2.4614: redrawing too much when 'cursorline' is set
Problem: Redrawing too much when 'cursorline' is set and jumping around.
Solution: Rely on win_update() to redraw the current and previous cursor
line, do not mark lines as modified. (closesvim/vim#9996)
c20e46a4e3
This doesn't match the patch exactly, because I missed some lines when
porting patch 8.1.2029, and these lines were removed in this patch.
This also makes win_update() always update for 'concealcursor' like how
it always updates for 'cursorline', as 'cursorline' and 'concealcursor'
redrawing logic has been unified in Nvim.
As redrawing for 'cursorline' now always only requires VALID redraw
type, it is no longer necessary to call redraw_for_cursorline() in
nvim_win_set_cursor().
Problem: Cursor line not updated when a callback moves the cursor.
Solution: Check if the cursor moved. (closesvim/vim#9970)

redraw_after_callback() is N/A. Nvim handles timers on the main loop.
vim-patch:8.2.4613: return type of swapfile_unchanged() is wrong
Problem: Return type of swapfile_unchanged() is wrong.
Solution: Use "int". (closesvim/vim#10000 Yeah!)

Problem: Highlight and match functionality together in one file.
Solution: Move match functionality to a separate file. (Yegappan Lakshmanan,

The use of 'softtabstop' to set tabSize was introduced in 5d5b068,
replacing 'tabstop'. If we look past the name tabSize and at the actual
purpose of the field, it's the indentation width used when formatting.
This corresponds to the Vim option 'shiftwidth', not 'softtabstop'.
The latter has the comparatively mundane purpose of controlling what
happens when you hit the tab key (and even this is incomplete, as it
fails to account for 'smarttab').
