Just noticed *another* issue with this function, and with some other
functions that were proposed earlier today.  The -- option is going
to be treated as a directory and trigger a separate invocation of the
"real" mkdir:  /bin/mkdir -p --

The good news is, if this actually happens, you'll probably get an error 
message telling you that it happened.

wooledg:~$ mkdir -p --
mkdir: missing operand
Try 'mkdir --help' for more information.

If you didn't see that, then it's pretty likely that your function was
not actually called.
