unhelpful error message: unknown option ""

After updating from 2.2.6 to 2.2.9, I had a problem with the
--no-parameter-indentation option I was using.

As it turns out, it was removed in favor of using
just --parameter-indentation0.  The documentation was not
updated.  That's a different bug.

When I tried to use 2.2.9 for the first time, I got this:

% indent -npro -nip
indent: unknown option ""
% indent -npro --no-parameter-indentation
indent: unknown option ""

That's not a very useful error message.  It looks like somewhere
between 2.2.6 & 2.2.9, it was broken due to a new way that long/short
options are parsed.

Note that it was broken in a different way in 2.2.6 (didn't print the
same # of dashes used on the command line - or didn't strip them
correctly), but at least it was more useful.

Anyway, here's a patch to fix the error message.
