[PATCH 0/3] rr/fmt-merge-msg replacements

I found a problem while writing the test for -1: the first patch is a correction for that; sorry I didn't detect it earlier.

The second and third patches are rewrites of the tests I submitted earlier- the rest of the file needs to be cleaned up to match this style. Thanks Jonathan.
