Oh, you're correct. In version 1.7.3.1-all-5, patch line 66 in
options.c removing (or commenting out) "FLG_MAKECHR_CHK | ", and
recompile. Then the above command will work as intended (I've just
tested it).
The reason why "--make-charset" and "--format" are declared incompatible
is that the "--format" specification won't be honored when you don't
specify any password files on the command line. In that case, the
entire john.pot will be processed by "--make-charset", without a hash
type filter that "--format" option could be expected to provide.

OK. Please try patching options.c as suggested above. Please let the
list know of your results - including whether the highly-focused custom
.chr file actually worked better for you or not.

Please re-post this as a follow-up to the correct thread (use your mail
reader's "Reply" feature on a message in that thread to ensure that the
headers are set correctly), then I might comment on it. I don't want us
to mix up the two threads - that would be a disservice to those browsing
archives of this list on the web.
Thanks,
Alexander
