mdocml: Remove function calls to res() and so forth in term_word().

[kristaps@mdocml.bsd.lv]

Log Message:
-----------
Remove function calls to res() and so forth in term_word().  These were
only used once and simply bloated the binary.  Also fix mchars_num2char
to correctly render the character instead of using atoi().  This makes
the conversation more strict, but it's more correct.
