redo-ifchange t/c.c
redo t/test
test.do would run all its subtasks even though it used 'redo-ifchange'. The behaviour is what we wanted, but it shouldn't have worked. So fix the bug in redo-ifchange, then change test.do to use 'redo' instead so it continues to do what we want, only for the right reason. (The bug is that 'redo-ifchange dirname', which runs dirname/all.do, didn't result in stamps getting checked correctly.) 2010-11-23 01:01:51 -08:00			`redo-ifchange t/c.c`
