The problem they're trying to address is that one can't reasonably 
expect a regular expression to handle cases where grave accent or 
apostrophe is itself being quoted `like this'.  The simplest way out I 
could think of, for the few doc strings where this comes up, is to use a 
different quoting regime to quote the grave accent and/or apostrophe.  
(One can imagine more complicated schemes of course, but they seemed 
overkill.)  In this situation the patch preferred curved double quotes 
where the original used `` and '', and curved single quotes otherwise.

I'm not proposing that, no.

No, they're just replacements for `` and '', which also don't have any 
special meaning.

Another possibility, which would also be fine and would be simpler, 
would be to replace all curved double quotes in doc strings with 
straight double-quotes.  I could easily do that if you prefer; it's no 
big deal either way.
