rockspec files are used by [Luarocks](https://luarocks.org/), the
most prominent package manager for Lua. Despite the different file
extension, these files are actually Lua files and should be syntax
highlighted as such.
For what it is worth, Neovim also does the same thing that I am doing in
this commit. They recognize both ".lua" and ".rockspec" as being Lua
files (and no other extensions, as far as I know).
Make String::Data use trivial copy of the short/long union to avoid
unnecessary branching there, inline release() as it can be elided by
the compiler on moved-from Strings.

Display a whitespace in place of the uncovered half of the codepoint.
(I know this is incorrect and we should be considering grapheme clusters
instead of codepoints, but this is a far bigger refactoring and another
can of worms to handle with terminal emulators).
Fixes#4262
Synchronized output does not work well with various terminals
(including the linux console). It should also be unnecessary when
not going through a slow link.
This will eventually be removed if it is not proven to be useful
to some users.
TerminalUI::suspend() is responsible for undoing all Kakoune's modifications to
the terminal state, actually suspending the process, then re-applying all the
modifications after Kakoune wakes back up.
Previously, the "undo" and "reapply" steps for termios settings were both after
the suspend point, so on some platforms they were incorrect when the user
arrived back at the shell prompt.
Now, the termios "undo" step is back before the suspend point, and the undo and
reapply steps should be in exactly reversed order.
Fixes#3488.
In terminals that support it, this sequence causes the terminal to not redraw
*its* output until the application has finished, reducing redraw flickering.
The sequence is defined in:
https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec
...and is apparently also supported by kitty and libVTE.
Fixes#3482.
insert blank seems to behave differently between terminals and would
be less efficient because it still has to shift all following characters
(that we will overwrite anyway).
Fixes#3437
Diff against known state and insert/erase relevant lines.
Erase everything first to avoid insertion invalidating lines that
get out of the terminal at bottom.
This should reduce flicker, by avoiding transient states where
info/menu windows are not displayed, and paves the way for proper
diffing of the screen.
