bug#45140: 28.0.50; rendering c source on the tty inside virtual console

[Alan Mackenzie]

Hello, rrandresf.

Firstly, sorry about missing your bug report last December.

Secondly, it's great to see somebody else using the Linux tty!

It looks like the fontification was unfinished on that screen.  For
example, strings and comments get fontified, but the variable
declarations didn't.  I hope that was a bug in CC Mode which has long
been fixed.  When that happens, there is often an error message in the
*Messages* buffer, which you can see with C-h e.

Was there anything else about the reduction in quality you mention?  I
think your yellow strings was something you configured yourself, for
example.

Is the problem still there in the savannah master branch, or what has
now become the Emacs-28 release branch?

Yes.  ;-)
