bug#16292: 24.3.50; info docs now contain single straight quotes instead of `'

I thought Eli was saying that it does just that: '...'.
What am I missing between what you two are saying about this?

Can you suggest how?  What should he look for?

I think this user might be willing to check, if we could tell
him how to do so.

Great, but I would still want Info+ to be able to easily test,
using Lisp, which is being used in the current Info buffer:
`...' or '...'.

As I mentioned, it is a lot better to try to fontify just the
proper pattern, rather than to try to fontify both possibilities
at the same time, just in case.

Such highlighting is never failsafe anyway (it can be thrown off
by a solitary quote symbol etc.), and if a regexp tries to match
both patterns at the same time then that just increases the
likelihood of doing the wrong thing.

So you are saying that if he got Emacs from a "standard tarball"
then '...' is the fault of the builder of that standard tarball.
Which would be whom?

I can try to find out where he got the Info files.  I don't
think he built them himself, but I have asked him and hope to
hear back.
