Thanks, this LGTM. Could you please add corresponding changes for the
documentation: the Emacs manual and NEWS? I will then install all of
that.
P.S. Sorry for a long delay in replying to your message.

Thanks for looking at this.

You will need to guide me for the latter, and I don't think
I want to get involved with the former (texinfo). For the
former, if you guide me I can propose text/wording, in case
that helps. Sorry if this doesn't fully help.

No problem at all, for that.

Sure, just tell what guidance you need.
In general, NEWS entries for new commands just need to name the
commands, and optionally say a sentence about what they do. The idea
is that the details will be picked up from the doc strings.

Providing text is good enough, thanks.

For NEWS:
New commands `apropos-local-variable' and `apropos-local-value,
which are buffer-local versions of `apropos-variable' and
`apropos-value'. They show buffer-local variables who names
and values, respectively, match a given pattern.
For the Emacs manual, node `Apropos':
`M-x apropos-local-variable'
Search for buffer-local variables whose names match
the specified pattern.
`M-x apropos-local-value'
Search for buffer-local variables whose values match
the specified pattern.
