bug#50968: 28.0.60; curly quote in lisp form in docstrings

[David Fussner]

emacs -Q
C-h f show-paren-mode

Here, I see (among other things):

-- begin quotation --

To check whether the minor mode is enabled in the current buffer,
evaluate ‘(default-value ’show-paren-mode)’.

-- end quotation --

The straight quote inside the form has become curly (unless gmail has
mangled it), preventing evaluation. This part of the docstring comes
from a template in
easy-mmode.el, so versions of it appear everywhere.

Thanks,

David.

P.S. Not using nativecomp, in case that's relevant.
