Well, we are getting picky, but I still don't think that counts as explicit documentation because it's tucked into a section describing the [] syntax.

Note, there is also a second and more explicit example of this syntax further down the man page. I would have to look it up, but I think it's something like /^(To|Received): *blah/

However, my point still stands that there is lovely documentation here on the rest of the syntax, and regular failure to use this construct in the patterns posted to this list, and so it might be nice to explicitly add an item on it in the "( )" section of the docs?

I'm going to drop it here though because it was only supposed to be a helpful suggestion and I think I missed my mark

P.S. I would be much more interested if someone had some thoughts on my other post about reformail. I'm writing a recipe which tries to send SMS messages based on incoming email and it's proving a little tricky
