patch: broken docstrings for functions from .elc.gz's

[Ivan Zakharyaschev]

        Hello!

A bug in Emacs 21.2 (and 21.3) has been reported by Sergey
Vlasov (a patch that aims to fix it is attached):

having life.elc compressed:

/usr/share/emacs/21.3/lisp/play/life.elc.gz

sometimes results in a broken docstring for `life'. More
precisely:

After Emacs startup:

C-h f life RET (the doc for the autoloaded function is fine)

M-: (load "/usr/share/emacs/21.3/lisp/play/life.elc.gz") RET
C-h f life RET (the full doc is fine)

M-: (load "/usr/share/emacs/21.3/lisp/play/life") RET
C-h f life RET (the doc is broken)

Debugging shows that `jka-compr-load' is called in the first
case, but it isn't called in the second one. Modifying a test in
src/lread.c fixes this bad behaviour.

Usually libraries are loaded in a way similar to the second case,
so usually the docstrings get broken.


As I can see from the CVS, the issue is still there in the main
Emacs development branch. The patch is for 21.3. (There is a
description of it inside.)
