[Message part 1 (text/plain, inline)]

Attached are patches to fix this in Emacs 27 and 28; they're
essentially the same, but with slightly different contexts around the
diff. I'm not sure if this is wanted for Emacs 27, but it's a small
bugfix, and combined with my patch in bug#39408 (and the GNU ELPA
version of Tramp to fix bug#44151), M-x gdb should work correctly for
Tramp. For Emacs 28, this is the only outstanding issue (that I know
of) preventing M-x gdb from working with Tramp.

The problem here was that `gud-last-frame', set in
`gdb-frame-handler', expects a local file path, so the full Tramp path
was confusing it.

(Note: I have a couple of patches in Tramp already that put me at the
limit for patches without copyright assignment paperwork. However,
I've already requested the form.)
