bug#19356: electric-pair-mode painful quotes in latex-mode

[Stefan Monnier]

Package: Emacs
Version: 24.4


   ./src/emacs -Q -f electric-pair-mode ~/tmp/foo.tex

then type a word, go back to before this word and try:

   C-M-SPC "

this will not surround the word in quotes as electric-pair-mode should.

Similarly, type

   hello " "

Notice how the second " inserts `""' instead of just modifying the ''
into a single ".  This same problem happens before a word.
