The syntax of the roff(7) .mc request is quite special
and the roff_onearg() parsing function is too generic,
so provide a dedicated parsing function instead.
This fixes an assertion failure when an \o escape sequence is
passed as the argument; the bug was found by tb@ using afl(1).
It also makes mandoc output more similar to groff in various cases.
