Use the freshly improved roff_getname() function

for the main roff request parsing routine, roff_parse().

In request or macro invocations, escape sequences now terminate the
request or macro name; what follows is treated as arguments.  Besides,
the names of user-defined macros can now contain backslashes (eek!).
