[Pkg-emacsen-addons] Bug#944249: gnuplot-mode does not work with emacs26

[Dima Kogan]

Hi.

It looks like the elpa-gnuplot-mode package is missing some of the
debiany emacs machinery: the files in

  /usr/lib/emacsen-common/packages/...

Somebody should look at the packaging, and figure out what we're missing
and add it. Likely it's just a line or two somewhere.

Nicholas: I'd be delighted if you fix this. Thanks for stepping up! I
don't think you need to do any NMUs to become a DD. Those happen when a
package needs to be fixed, but its maintainer is not available for
whatever reason (NMU = non-maintainer upload). And until you're a DD you
can't upload anything yourself anyway.

You should work on the issue, and when you're done, let me know. I'll
take a look, and then I can do the upload for you.

The location of this package is a historical artifact. It was originally
team-maintained in collab-maint. Then when it was converted (as it turns
out unsuccessfully) to a debian elpa-... package, it was moved to the
emacs team (by changing the Maintainer field). But we didn't move the
repo. I'd rather leave it where it is: there's little downside to
leaving it, and if we do move it, there're a lot of little things that
could be messed up, and then we'd have to fix them. It's not worth the
effort, I think.

Feel free to add yourself to the Uploaders, if you want to.
