Subject: bug#4359: bug#15775: 24.3.50; "WARNING: terminal is not fully functional" in Comint and Eshell

This change makes "git grep" work as a grep command with `M-x grep' (if
you remove --null).  It's shouldn't have a negative impact on much
anything else (because no pagers should be used anywhere here), but
perhaps it should be done in grep.el instead of compile.el...

Anybody got any comments?
