 I've just been going through the source, and it's been a long while since I 
last used C, but I think I can answer my own question:

 Yes, the subpattern matches are stored globally, in the array re_matches 
(defined in filter.c/h, used in macros.c). I can't think of any logical 
reason why it would be designed this way intentionally, so I suspect it's an 
oversight/bug. Unless there's something I've missed?

 Is there any official way to report bugs, or is this as official as it 
gets? ;)
