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
This fixes a bug in how the Lua scripts handle new comment lines.
Currently if we have a comment that is indented, when we add a new line
it inserts the `--` prefix before the automatic indentation.
```
--ABC
-- XYZ
```
After the fix, it correctly inserts the comment prefix after the
indentation:
```
--ABC
--XYZ
```
The solution I used is inspired by the ruby.kak script.
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.
