Re: Help hyperlinks only work when auto-compression-mode is enabled.

'Evening, Richard!

[ Quick recap of the problem:  Disable auto-compression-mode; do C-h f
  revert-buffer <CR>.  Put point over `file.el' and press <CR>.  The
  source file doesn't appear, because Emacs-22's "make install"
  compresses our source. ]

Apologies:  When I wrote my two posts in this thread, I'd convinced
myself that my patch fixed the problem purely for the Emacs sources.
Which is complete and utter nonsense, of course.

The only way to uncompress _only_ the emacs sources is to create some
variable containing "/usr/local/share/emacs/22.1/lisp" and test it.
YUCK!!  I don't think that's the right thing to do.

We either decide that that <CR> will ALWAYS find compressed files in
that context, or we accept the hit with C-h f and disabled a-c-m.  I
don't think the latter is acceptable, since we don't output an error
message which is at all helpful.

I think the best thing is NOT to compress our source files with "make
install".  The compressed lisp directory contains 9.5 Mb of .el.gz
files.  Uncompressed, it's a bit around 38.5 Mb.  This saving of ~30 Mb
doesn't seem worth the hassle it causes.

What do people think?
