I'm comfortable with this language by and large.  I prefer the alternative

IHAVE, POST, MODE READER, LIST EXTENSIONS, and QUIT are not streamable and
if this text is adopted, this should be noted in their descriptions.

I'm not sure about GROUP.  If GROUP fails, it could cause cascade failure
of a lot of the remaining commands in the stream, although this isn't as
bad as if IHAVE or POST fail.
