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'.

Those two cases look simple (replace ` and the first matching ', the second ` would be skipped), but if the apostrophe were quoted, it'd have to be escaped: `\''.

And it's not very simple, but a regular expression can distinguish between an escaped and an unescaped character. Examples:



Though granted, that's a lot of backslashes.

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.

Not a big deal indeed, but consistency would be preferable IMHO.
