X * Parser for stupidly-formed RFC822 addresses. It has been tested on
X * several bizzare cases as well as the normal stuff and uucp paths. It
X * takes a string which is a bunch of addresses and unscrambles the first
X * one in the string. It returns a pointer to the first char past what it
X * unscrambled and copies the unscrambled address to its second argument.
X *
X * It does NOT deal with trailing (comment) strings --
X * <whoever@somewhere> (This is a comment)
X * ^unscramble_addr return points here
X *
X * It also does not deal well with malformed <addresses> --
X * <whoever@somewhere,nowhere>
X * ^unscramble_addr return points here
X *
X * In each of the above cases, the string "whoever@somewhere" is copied
X * to the second argument.
X *
X * Nothing is done to un-<>ed route-less RFC822/976 addresses, nor to
X * uucp paths, nor to mixed-mode addresses not containing a route.
X * Hopelessly scrambled addresses are not handled brilliantly --
X * @some.dumb.place,@any.other.place:sys2!user%sys3@sys1
X * parses to
X * sys2!user%sys3@sys1
X * i.e., the route is simply dropped.
X *
X * If UUCP is defined, a little more work is done with @: routes. The
X * mangled address given above will unwind to
X * some.dumb.place!any.other.place!sys1!sys2!sys3!user
X * thanks to intelligence in bang_form().
