Thanks.  That's likely to be quite practically useful to many people over 
time, including me.  =:^)

(FWIW, while I mentally appreciate that wikis are there to be user-
edited, in practice I seem to treat them like I do most of the web, read-
only, and never actually seem to get around to changing them at all.  
OTOH, I've always enjoyed the give and take of newsgroups and mailing 
lists and in practice spend quite a bit of time replying to posts, 
hopefully helping others there, which I know I do based on the thanks I 
get.  So I really /can/ thank you for putting that on the wiki, since 
while it's likely to make my job replying to posts easier, in practice 
it's something I'd be extremely unlikely to change on the wiki myself, 
even on wikis like the btrfs wiki which I highly value and have spent 
quite some time reading and much more replying on the related list, 
because for whatever reason I personally just seem to have an easier time 
replying on-list than I do editing wikis.  But I'm sure glad others get 
around to editing them. =:^)
