Yes, and I didn't apply them to the originals as I fixed them.  In
retrospect, this was not smart.

I attached some fixes that I fished out of the rather noisy diff.  I
think I got most of them.  The majority aren't really for `bugs', at
least not serious ones.  They mostly correct wrong function names in
your error macros.

I noted some discrepancy in argument order between the srfi-14 text
and Olin's reference implementation.  For those functions that take a
string and a `criterion', the srfi (usually) lists the order as
`string' `criterion', but the reference implementation often switches
them around.  The functions string-every and string-any are
exceptions:  the spec orders their arguments as `criterion' `string'.

I flipped several arguments around to match the srfi spec instead of
the reference implementation.

That thought occurred to me as I was working, but as I had already
started, I just plowed on.  I'll use mine until yours get integrated
into the Gambit distribution.

What advantage does the more complicated error checking have over the
simpler checking that I put in?  Is there more to it than just
consistency with the Gambit runtime?
