I wasn't aware of it.  I was just basing my off-the-cuff suggestion on what the
code was apparently trying to do here.

But `record-window-buffer' is apparently quite a bit more than just
(select-window (selected-window)).

Should `record-window-buffer' be used in its place at this occurrence?  If not,
should another function be defined to do only (select-window (selected-window))
- essentially an alias to better communicate the intention?

You're the expert here, not I.  My feeling is just that using (select-window
(selected-window)) to take advantage of a less-than-obvious side effect is
obfuscating, not clever or wise.

Without an informative alias for this action, the code really needs to be
commented to indicate the unobvious intention/effect, at the least.  But is
probably better to have a function name & doc string communicate this than code
comments and bug reports.
