bug#24710: 26.0.50; Feature request: Replace double quotes in electric-quote-mode

[Philipp Stephani <p.stephani2@gmail.com>]

Currently electric-quote-mode only replaces ' and `.  I propose that
it also replace " with a left double quote after spaces, newlines, and
open parentheses, and with a right double quote after alphanumerics and
other punctuation.
