kak-lsp uses these faces to mark errors inside the buffer, instead of the Error
face which is much more jarring, and which does not have an associated warning
face. Since the :spell command marks errors inside the buffer, it's also updated
to use this new face.
Adding these faces to Kakoune makes it more likely that colorschemes will
automatically do the right thing when used with kak-lsp, and makes it possible
to use a subtle appearance (like curly underlines) for in-buffer errors while
keeping Kakoune errors bold and jarring as they should be.
This commit removes declarations and mentions to the built-in `bold`
and `italic` faces.
While they could be a user-friendly way of customising how tokens
are emphasised in Markdown documents (similarly to the
`$LESS_TERMCAP_*` environment variables for `man` pagers), most other
markup languages do not have the concept of "strong" and "emphasis"
but refer directly to the font style/weight.
The faces were also not even set by default to highlight as their
names implied, so having markup language support scripts directly
use the +b and +i face attributes is more consistent.
This commit adds a `documentation` face to the builtin themes, used
to highlight common documentation syntaxes:
/**
* JavaDoc
*/
/*!
* QtDoc
*/
/// Inline documentation
## Inline documentation
The face is only an alias to the `comment` one for now.
Closes#1944
