Subject: get_maintainer: Don't check if STDIN exists in a VCS repository
X-Git-Tag: v4.8-rc2~29
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=aec742e8e1cf05114530bdef8051238b6dbb4052

get_maintainer: Don't check if STDIN exists in a VCS repository

If get_maintainer is not given any filename arguments on the command line,
the standard input is read for a patch.

But checking if a VCS has a file named &STDIN is not a good idea and fails.

Verify the nominal input file is not &STDIN before checking the VCS.
