From: Michał Kiedrowicz Date: Mon, 9 May 2011 21:52:08 +0000 (+0200) Subject: git-grep: Bail out when -P is used with -F or -E X-Git-Tag: v1.7.6-rc0~18^2~5 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=258a6188496fe5131203905b6cd596af69312247;p=git.git git-grep: Bail out when -P is used with -F or -E This patch makes git-grep die() when -P is used on command line together with -E/--extended-regexp or -F/--fixed-strings. This also makes it bail out when grep.extendedRegexp is enabled. But `git grep -G -P pattern` and `git grep -E -G -P pattern` still work because -G and -E set opts.regflags during parse_options() and there is no way to detect `-G` or `-E -G`.
