You're welcome... :)

I think that's me... :)

Thanks for the report, I've released a new version (0.4.4) which fixes
this.

If I understand the Gray streams proposal correctly, this isn't an
incompleteness in FLEXI-STREAMS, but a problem in CMUCL's Gray streams
implementation.  Are you using the newest version of CMUCL?  Have you
asked on their mailing list?  (It is also not clear to me why the
problem only surfaces with the longer URL because URL-ENCODE has to be
called in both cases.)

Cheers,
Edi.
