Length of recent X-Hashcash cookies?

Hi.  I have been using X-Hashcash for a while, but the recent cookies
are long (>80 characters), which look quite ugly.  I know this is not
a violation of any specification, but that doesn't mean they don't
look any less ugly.

Anyone care about this?

Could leading '0' in the last field be removed, for instance?

Thanks,
Simon

PS.  This message has a cookie for a gmane.org newsgroup.  This is
because Gnus doesn't handle X-Hashcash in news->mail gateways
properly.  If someone has any suggestion how it should work, that
would be appreciated.

PPS.  How about renaming X-Hashcash: to Hashcash:?  The 'X-' prefix
also look ugly, and was only discussed in RFC 822, not in the current
RFC 2822.
