[PATCH v2 14/18] fsck: Allow upgrading fsck warnings to errors

[Johannes Schindelin]

The 'invalid tag name' and 'missing tagger entry' warnings can now be
upgraded to errors by specifying `invalid-tag-name` and
`missing-tagger-entry` to the receive.fsck.error 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).
