I don't object in principle, but in this case it looks like the
implementation based on cl-do needs much more complex code than the
original?  If so, I'd prefer the original, simpler and
easier-to-understand code.

> To ease the review process, I have broken down the changes into two

The commit log message is not detailed enough: it doesn't mention the
functions you modify.  Please see the conventions we follow for log
messages described in CONTRIBUTE, which also mentions useful Emacs
functions which will help you format the log message according to our
conventions.

Thanks.
