bug#8928: 24.0.50; can't open member of tar file in gnus *Article*

[Tom Tromey]

I got an email message with a .tar.gz attachment.
Gnus now opens this in-place in the *Article* buffer -- very cool!
However, I can't seem to open the file contained in the tar.
Middle-clicking on the file name (per the tooltip), or using RET there,
just gives:

widget-button-press: Buffer is read-only: #<buffer *Article nnml:mail.other*>

I think it just calls "/bin/tar tvzf -" (via `set-auto-mode'), so
getting that to work reliably is kinda difficult, I think.

Gnus would have to instate `tar-mode' on a part of the buffer, and I
don't think that's practical.

I can see how it might be difficult.  However, it seems worthwhile.
Perhaps it can be done without requiring a solution to the two major
modes problem -- by reusing tar-mode functions.

Also, if this is impractical, then why buttonize the file names in the
first place?  I couldn't figure out what these buttons were supposed to
do; clicking on them just gives an error.

Gnus just calls whatever mode that seems likely, more or less.  So
calling tar mode on the part isn't something that somebody has thought
of happening, most likely, but is just happening as a fallout of the
general code.

This has been implemented in Ma Gnus, so it'll probably be in Emacs 24.2
or something.
