So while you can combine flags for *most* programs, you still won't 
be able to say things like

	git clean -qdx

just because that's still a shellscript, and doing any fancy argument 
parsing in shell is just painful.

Indeed... but for my personal shell scripts I like to use a construct
like the following for parsing args:

   while :; do
     case "$1" in
        ... lots of cases to handle normal args ...

       -[!-]?*)
         # split concatenated single-letter options apart
         FIRST="$1"; shift
         set -- `echo $FIRST | $SED 's/-\(.\)\(.*\)/-\1 -\2/'` "$@"
         ;;

       -*)
         # unrecognized option
         unrec_opt "$1"; exit 1;;
       *)
         # non-option
         break;
     esac
   done

I'm sure there are problems with it, but it generally seems to work
pretty reasonably for short options.
