Fix segfault when adding an invalid default-region highlighter
RegionsHighlighter::create_region() validates the highlighter type argument
but RegionsHighlighter::create_default_region() assumes it is correct,
segfaulting from dereferencing a null pointer if the given type isn't in
the highlighter registry HashMap.
@PJungkamp reported this in https://github.com/mawww/kakoune/issues/4959
with a simple recipe to reproduce:
:add-highlighter shared/test regions
:add-highlighter shared/test/ default-region invalid highlighter
:add-highlighter window/test ref test
Validate the type argument in RegionsHighlighter::create_default_region()
in the same way as RegionsHighlighter::create_region().
