Log Message:
-----------
merge kristaps@' bugfix from HEAD:
Fix a corner case where \H<nil> (where <nil> is the \0 character) would
cause mandoc_escape() to read past the end of an allocated string.
Found when a script scanning of all Mac OSX manual accidentally also
scanned binary (gzip'd) files, discussed with schwarze@ on tech@.
