Some variable name documentation attached.

I haven't renamed them for various reasons, e.g., to keep 'blame' usable
and to maintain similarity to other functions which may also use the
same short names.

I'm planning to commit this with distinct X-Seq numbers such as
39309/{0001..0011} — didn't want to send 11 separate emails for such
trivial changes.
