New method (actually, there are two, I see on re-checking --
(a) and (b) in my list above): understood.  Will submit
revised patch without them, and a separate patch for 2.5
with only the new methods.

Docs: I have verified that none of these are unnecessary
rewordings.  Some are fixes for typos or bad English.  Most
of the rest are of minor clarifications or corrections, but
are solid improvements.  Please point out specific changes
whose value you doubt, and I will explain (or remove if
persuaded, of course)!
