I've uploaded a new url.sty to CTAN/UK: version 3.0
It contains the fix for the reversal-of-penalties just reported,
It has substantial modifications in the area of grouping and encapsulation of the lists of break-characters, automatic adjsutment to font encoding, definitions of new url styles.
I think there are previously-unreleased changes improving handling of #, and better separation of verbatim, breaking, and formatting (which were supposed to be version 2.)
Users: Please report any new problems asap.
i've installed the new version as macros/latex/contrib/misc/url.sty replacing the old one. thanks for the upload.
