On the other hand, you'll be able to dynamically determine which quotes 
to use, depending e.g. on the locale.

It still doesn't have the fancy quotes directly in the source code: they 
seem to be generated dynamically, similarly to the suggestion above:

https://github.com/gcc-mirror/gcc/blob/06fa1266fac43778983b3925ad048748297db38c/gcc/c-family/c-lex.c#L526

Neither of those should be particularly hard to implement.

I don't see why we'd still need that, but the patch seems generally 
useful either way.

Two reasons. Neither of them is big, but the improvement from the 
transition to different quoting method is not huge either.

- Using unicode for markup is a complication (e.g. with certain mail 
clients, but some other instances might come up).
- I don't like having two standards for quoting. And if quotes are 
agumented with font-lock, all the existing Elisp out there will be 
displayed with modern quotes automatically.
