M-x grep: /dev/null appending workaround

M-x grep: /dev/null appending workaround

[Dan Jacobson]

I have outsmarted M-x grep's /dev/null appending:
(grep "zgrep -n -e TLS main*|colrm 77 #") for example.
Making zgrep -n -e TLS main*|colrm 77 # /dev/null
be what gets executed. You might want to document this workaround, or
better yet, stop appending the /dev/null hack.

You have outsmarted yourself.   Use M-x compile instead of M-x grep.

I would use quotes around expression:

        ... -e 'TLS main*|colrm 77 #'

The /dev/null is unavoidable (because of old grep/egrep implementations)

(I was only looking for "TLS", and my # was purposely naked to wipe out
all following junk, i.e., /dev/null.)
