mdocml: Use the freshly improved roff_getname() function for the .de

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
Use the freshly improved roff_getname() function
for the .de parsing routine, roff_block(),
to correctly handle names terminated by escape sequences.
Besides, this saves us 20 lines of code.
