Subject: 30.0.50; `format-message' does not allow displaying "`" and "'"
 verbatim

Hi,

Following up https://list.orgmode.org/87k027af5x.fsf <at> localhost/T/#t
and https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=62dc49509c8962bd2a19c4c4475fc616eebdfde8

`format-message' and thus also `warn' unconditionally replace _all_ the
instances of "`" and "'" in the message:

    This acts like ‘format’, except it also replaces each grave accent (`)
    by a left quote, and each apostrophe (') by a right quote.

However, sometimes, it is desired to keep these chars literal.
For example, `org-assert-version' displays a warning that suggests Elisp
code:

(warn "...
   It is recommended to put
    (straight-use-package 'org)
...")

Replacing "'" is undesired here and will make copy-pasted Elisp code
incorrect.

Would it be possible to introduce some kind of escape mechanism in
`format-message' to produce literal "'" and "`" when needed?
