A common mistake is to provide a filter which fails unwantedly. For example, this will stop in the middle: git filter-branch --env-filter ' test $GIT_COMMITTER_EMAIL = xyz && export GIT_COMMITTER_EMAIL = abc' rewritten When $GIT_COMMITTER_EMAIL is not "xyz", the test fails, and consequently the whole filter has a non-zero exit status. However, as demonstrated in this example, filter-branch would just stop, and the user would be none the wiser. Also, a failing msg-filter would not have been caught, as was the case with one of the tests. This patch fixes both issues, by paying attention to the exit status of msg-filter, and by saying what failed before exiting.
