Subject: (check_symlink_color): New variable.
X-Git-Tag: FILEUTILS-4_0k~20
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2be3dc067ac98bbf165f8d0dbd7c799128cb9d0b;p=thirdparty%2Fcoreutils.git

(check_symlink_color): New variable.
(main): Set it if we need to check for dangling symlinks when
displaying colors.
(gobble_file): Check check_symlink_color instead of print_with_color.
