Meh, I suspect a lot of people don't know that term.  Perhaps something
like "The generated queries are executed in the order in which the rows
are returned, and left-to-right within each row if there is more than one
column."

I like it. Change forthcoming.


Changes since last submission:

Patch attached. Changes are thus:
- rebased
- pset.gexec_flag unconditionally set to false at end of SendQuery
- wording of documentation describing execution order of results
- rebasing allowed for undoing the re-wrap of enumerated slash commands.

Still not changed:
- exuberant braces, can remove if someone wants me to
