Uncompface is still far from robust in the face of maliciously or
erroneously constructed faces.  I just received an X-Face: header
in which the X-Face: keyword was duplicated.  Not only did this face
decode incorrectly, but subsequent, correctly formed face headers
were also corrupted.  Let's add bullet-proofing of uncompface to the
TODO list.
While your adding this, you could presumably delete John's now done TODO:

I believe this is not the only obsolete TODO entry.
Mark.
