Re: Emacs 21.3.50 grep.el/executable.el problems

[Markus Rost <rost@mathematik.uni-bielefeld.de>]

I got the impression that the grep/executable problems don't get
fixed, because there should be perhaps a more extensive change.
However, it seems that quite a few people spent some time to fix it,
probably because grep is used a lot.

I suggest following simple fix, at least as a temporary solution.
I'll install it, if one of the maintainers agrees.
