[Austin Clements]

LGTM.

Quoth Mark Walters on Nov 12 at  8:10 pm:
> This is v4 of this patch set. v3 is at id:1383932419-12533-1-git-send-email-markwalters1009 at gmail.com.
> 
> David found a bug in v3 which I tracked down to some match-data being
> over-written. This included the bugfix
> id:1384076682-16872-1-git-send-email-markwalters1009 at gmail.com which
> is folded into this series as the second patch.
> 
> The diff v3+bugfix is below: it does the save-match-data as Austin
> suggested, and it removes an accidental added comment which I put in
> when finding the bug.
> 
> I have also left off the last "testing patch" (a patch that added some
> functionality to make it easier to test the help routine but not
> something that should be added to mainline)
> 
> Best wishes
