libgedit-gtksourceview-300-common: Markdown syntax highlighting regression/incomplete on gedit since Debian 13 is using this package

[Julien ROBIN]

Package: libgedit-gtksourceview-300-common
Version: 299.5.0-1
Severity: normal

Dear Maintainer,

I noticed a regression, since using Debian 13, Gedit syntax highlighting is missing a part of the Markdown syntax, the 3 backticks code span, which, placed above and under some lines, should make the affected lines shown as code.

The 3-backticks-code-span is missing from markdown.lang file :
 - /usr/share/libgedit-gtksourceview-300/language-specs/markdown.lang

Copying the `/usr/share/gtksourceview-4/language-specs/markdown.lang` (which seems to cover the 3-backticks-code-span) in place of `/usr/share/libgedit-gtksourceview-300/language-specs/markdown.lang` seems not to work however.

So I edited the `/usr/share/libgedit-gtksourceview-300/language-specs/markdown.lang` to re-enable the 3 backticks code span (see attached).

I don't know if there are others syntax highlighting regressions since gedit is making use of libgedit-gtksourceview-300, but this one is sure breaking the highlighting of approximately all of my *.md files.

Hoping this report may help getting this solved for everybody!

Best regards,
Julien ROBIN
