bug#12214: rmail-output-read-file-name Error in Summary (with Patch)

[T.F. Torrey]

Hello developers,

I'm happy to report a bug and a fix.

Description: When in an Rmail summary buffer,
rmail-output-read-file-name looks for matches in the summary buffer
rather than in the rmail buffer, and thus fails to find the proper
match. The patch below corrects this behavior.

ChangeLog entry: make rmail-output-read-file-name use rmail-buffer when
in summary

I was unable to download the most recent Emacs from bazaar, but I was
able to get the source from the Ubuntu archive, and I think it is
current in this regard. Because of this, I also had to make a slightly
different diff, but I think it will work. It's only a two-line change
anyway.
