Alexis S. L. Carvalho <alexis@cecm.usp.br> [Sat, 28 Apr 2007 17:55:45 -0300] rev 4387
run-tests.py: pass -L/--label to simplemerge
This should give us conflict markers that don't change from one run
to another.
Remove some sed's/egrep's from some tests.
Use patch.patch() when checking for patch availability.
The test is closer to what we want to know. It also makes sense when you deal with patched versions of patch() as most people do under win32.
