Thanks, I liked the second one better, so I pushed it.

Please note that the doc strings and the manual text included a few
typos, and also used the passive tense too much.  See the follow-up
changes I pushed after your changeset.  In the future, I suggest to
use the Emacs spell-checking capabilities to spell-check the text in
the manual and also the comments/strings in the C/Lisp sources.
