Ingo,

Isn't it easier just to do as in the enclosed patch?  man(7) doesn't 
seem to care at all about the date, so let's stop pretending that it 
does and just mandoc_strdup() instead of mandoc_normdate().  This patch 
also moves mandoc_normdate(), mandoc.c, into mdoc_normdate(), mdoc.c.

Thoughts?
