Existing configuration files will keep working for now since the old name with dashes is still recognized by the config parser.

Suggested by stsp@. This makes possible to tell if 'got patch' used a merge-base from the repository for the 3-way merge or did a simple search/replace operation. While here update the tests to look for the 'G' status and the manpage, which was also missing the documentation for the 'C' status in got patch. ok stsp@

So that 'got log -S' can match also the author and committer name, and the commit ID too. ok stsp@

-s for short. Moves log search to -S. Patch by Evan Silberman

add a flag to got_patch to reverse a patch before applying and the -R flag for `got patch'. ok stsp@

Move some bits from the libexec helper to the main process so we know if the patch was generated by git or not and finally document the automatic stripping of a/ and b/ prefixes added by git-diff(1). ok stsp@

Augment got_patch_progress_cb by providing the hunks that were applied with offset (or that failed) and the recoverable error encountered during the operation (bad status, missing file, ...) got_patch now proceeds when a file fails to be patched and exits with GOT_ERR_PATCH_FAILED if no other errors are encountered. While here, also add a test for the 'hunk applied with offset' case and shrink test_patch_dont_apply and illegal_status by taking advantage that 'got patch' doesn't stop at the first error. (And add some other cases to illegal_status too.) discussed with and ok stsp@

with lots of help from stsp for the manpage bits!

Simplify some phrasing, explain what preconditions `got patch' has and what happens to the work tree when an error occurs.
