unexpand: correct behavior for --first-only --tabs=4
Prior to the patch, both -f and --first-only are in all cases either no-op or ignored. Without --tabs, --first-only is the default so specifying it is a no-op. With --tabs, --all is implied, and --first-only is intended to reset this. function old new delta expand_main 690 694 +4 Signed-off-by: Mark Edgar <medgar123@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
