[PATCH] init: don't reset core.filemode on git-new-workdirs.

[Madhu <enometh@meer.net>]

From: Madhu <enometh@net.meer>

If the .git/config file is a symlink (as is the case of a .git created
by the contrib/workdir/git-new-workdir script) then the filemode tests
fail, and the filemode is reset to be false.  To avoid this only munge
core.filemode if .git/config is a regular file.
