options: commandline: print error type for parse failures
If parsing an option fails, print a string corresponding to the parse
function return value (M_OPT_MISSING_PARAM etc). The primary
motivation is that the parsing code already outputs messages
explaining most problems, but does not itself print anything in the
missing parameter case. Before double-dash --options such errors were
rare (or rather they resulted in the next commandline argument being
silently misinterpreted as an argument to the previous option
instead); but now an argument like "--ss" should give a better
indication about the problem than just "Error parsing option".
