We are not likely to take any patches that adds Plan9 mk support to
make-mode.el, even if the change is very minimal.  It will add to the
maintenance burden going forward, and it is just not widely used enough
to be worth it.

I recommend creating a new major mode and submitting it as a GNU ELPA
package instead.  This can be based on make-mode.el, a complete rewrite,
or written from scratch, as you prefer.  It's probably best to avoid
code duplication, perhaps by inheriting make-mode, if that makes sense
here.

I will be closing this bug as wontfix, but please don't take that as an
indication that a Plan9 mk package won't be a welcome addition to GNU
ELPA.  On the contrary, we will be happy to distribute such a package,
so that it can benefit users interested in this.

Please request your package to be included when it is ready.  The
process for that is described here:

Please submit a separate bug report for this if it's still an issue, and
include a clear description of the issue.  I couldn't make it out from
the above.
