largefiles: missing largefiles should not be committed as removed
Largefiles can easily become missing - for example if it simply isn't available
or the download fail. It might even be convenient to be able to work that way
in some cases.
But commiting missing largefiles as if they had been 'hg remove'd is plain wrong.

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:
