bug#51605: Fwd: [PATCH] Update themes to support mode-line

[Pedro Andres Aranda Gutierrez]

Hi Eli,

point taken... if it isn't the fringe, then something else. I find it more problematic to have the same face for the buffer and line numbers.

And it's from the conceptual point of view that line numbers aren't buffer and therefore should have a different face by default.

OK, I use a couple of themes that happen to have a shadowy background for the fringe, but I could live with anything that makes this _conceptual_ difference visible.

(Just my .2c worth of experience; when I edit/correct Python exercises from my students, this visual difference helps me detecting indentation errors much quicker; my student's experience: different line number and buffer faces help them editing and therefore adopting Emacs as their editor of choice for Python and from there they explore org-mode for their short papers and presentations and they become regular users in no time ;-) )

Best, /PA

What happens if there's display margin between the fringe and the line
numbers?

In any case, I don't understand why you insist on using the fringe as
the basic face here.  The line numbers have nothing to do with the
fringe, and if you assume that the fringe's background will always be
a pale, shadowy color, that assumption can easily be false.  E.g., in
my sessions the fringe has a very vivid color.  It's a problematic
dependency.
