Revert commits might be blocked by YACC in a couple cases:
1. When a commit regex is enabled. Revert commits typically start with 'Revert ...' which might not be allowed by a commit regex
2. When an issue JQL matcher is enabled. This can be a problem because revert commits typically include the commit message of the original commit, which might contain an JIRA issue that doesn't match the current JQL matcher (for example, it might be an older issue that has been closed)
It would be nice if there was a configurable option to allow YACC to ignore revert commits. This would work similar to the exclude merge commit option.
