Thanks for the bug report and patch, but I ran into a problem with the
patch. Suppose I do this:
emacs -Q
M-x electric-quote-mode
M-x customize-variable RET electric-quote-string, set it to t, save
M-x python-mode
'abc'
That is, I type apostrophe-a-b-c-apostrophe in Python mode. With the
patch, the buffer will contain:
'abc’
The opening apostrophe is OK, but the closing apostrophe is considered
to be inside a string so it is transmogrified into a right single
quotation mark. A Python programmer would want both to be apostrophes.
I'm not sure, I think if a user has electric-quote-string enabled, that's the behavior they want, because it's inside a string. However, I can see that both approaches are valid. There is probably no good way that would work in all circumstances.
