minimal/do: 'redo-ifchange' with no parameters shouldn't try to build all.

Browse source 
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.
