    rebase: fix on-line location extraction from devhelp files
    
    Fix regex to match online location:
     - only require one space before online=..
     - don't require slash after online="https://..";
    
    Fix follow-up sub on match:
     - match.groups(1) returns a tuple, use match.group(1) to
       get a string back which is what we need to feed to re.sub()
