The ‘..’ convention in doc strings was introduced in 2015, but never
really took off -- even after seven years, there were only a dozen
usages in-tree, so it seemed time to revert back to the previous
convention (which is to use `...', which is then converted to ‘...’ on
display).  The problem with ‘..’ is that nobody still knows how to type
it, and if you're working on a display that can't display those
characters, the help texts are all messed up.  (Which isn't the case
when using `...'.)

I forgot to update the documentation here, though, so I've now done
that.  Perhaps it's a bit early to issue a compilation warning for this,
though, since it's probably found in the wild here and there, so I've
now disabled that in Emacs 29.
