Subject: [PATCH] contrib: add git gcc-style alias

I thought it could be easier to use check_GNU_style.py.  With this alias,
'git gcc-style' will take a git revision as argument instead of a file, or
check HEAD if no argument is given.

contrib/ChangeLog:

	* gcc-git-customization.sh: Add git gcc-style alias.
