minimal/do: 'redo-ifchange' with no parameters shouldn't try to build all. It should just build nothing. Because sometimes you want to do something like: redo-ifchange $(find -name '*.c') And the find doesn't return any results. This is consistent with what real redo does. Added a test to confirm that it works. 2011-02-26 18:01:31 -08:00			`redo-ifchange`
