This should now have been fixed.

However, the test suite (make check) threw up another discrepancy, in a
test called
electric-pair-whitespace-chomping-2-at-point-4-in-c++-mode-in-strings.

That's with electric-pair mode enabled, and
electric-pair-skip-whitespace set to 'chomp.  The buffer, at the start
of the test, looks something like:

    " (

      ) "

.  With point just after the (, type a ).  The expected result is that
everything up to and including the existing ) gets "chomped", leaving
the buffer looking like:

    " () "

.  This no longer happens in C++ mode, and it is not clear that it
should.  In the original buffer, ( and ) are not in the same string,
since the opening string ends at EOL, there being no backslash to
continue it.

If there were escaped newlines in the buffer, I don't think the "chomp"
would work, because elec-pair.el doesn't recognise escaped newlines as
whitespace.

Comments?
