The 'invalid tag name' and 'missing tagger entry' warnings can now be upgraded to errors by specifying `invalidTagName` and `missingTaggerEntry` in the receive.fsck.<msg-id> config setting. Incidentally, the missing tagger warning is now really shown as a warning (as opposed to being reported with the "error:" prefix, as it used to be the case before this commit).
