Subject: bug#6843: 23.1; grep-mode and filenames with colors

From: Ethan Glasser-Camp <[email-masked]>

grep-mode highlights matches based on the presence of a pair of colons
around a number. But, for example, if you do this:

ethan@joker:~$ mkdir test
ethan@joker:~$ echo 'Hello' > test/10:45:20.txt
ethan@joker:~$ emacs -q

M-x rgrep <RET>
Hello <RET>
~/test <RET>

The results will mis-highlight 10:45:20, coloring "45" as the line
number (when it is part of the name of the file). Correspondingly,
if you do

M-x grep <RET>
Hello 10:<TAB> <RET>

The same thing happens. It's not possible to automatically jump-to-line
when this happens.

Thanks for your time,

Ethan
