(browse-url-path-regexp, browse-url-short-regexp,

browse-url-regexp): Variables deleted.  (They were moved to
thingatpt.el.)
(browse-url-filename-alist): Default now has leading ange-ftp-type
patterns so that the "^/+" pattern doesn't mung such names in
advance.
(browse-url-file-url): Don't do explicit ange-ftp path munging
here.
(browse-url-netscape-program): Doc addition.
