EditBug:10100 Email and website fields in author update interleaved with semicolons

I tracked this down in the source; the problem is that PrintMultField() expects a sequence as its last argument, but the viewer is passing the plain ol' string (containing a semicolon-separated list of email addresses). Python will treat a string as a sequence of characters, though, so PrintMultiField() interprets it as a list of 1-character email addresses, and lists them all, separated by semicolons.
