I'm presuming that was meant to be:

  PORTOPTION="\"-o$2\" "

or in fact, probably SSH_O_OPTS=...

Anyway, I cannot get that quoting to work -- it seems to leave the
quotes in and then use it as a hostname -- I've tried a few variations
with no luck so far.

Also, I'd say (assuming the quoting worked) that it should actually be
something like the following, in order to allow -o to be specified more
than once:

  SSH_OPTS="$SSH_OPTS \"-o$2\""

with the -p option similarly doing:

  SSH_OPTS="$SSH_OPTS -p $2"

and replacing PORTOPTION with SSH_OPTS throughout.

I'm also mildly concerned about how appropriate the -o options that
people specify are going to be for the diagnostic probes, and other ssh
calls.  I'm assuming that they'll be harmless, and perhaps essential,
so should be added to every ssh call in the script.

anyway, here's the failed attempt at that patch -- suggestions as to
how to make the quoting work properly would be welcome:

Fair enough, I've added that.
