Open an AWK file, and ensure that electric-pair-mode is enabled. It
seems that some character pairs like braces or parentheses are
automatically paired, while others like apostrophes or double quotes are
not.

I have managed to narrow this bug to the function
`c-electric-pair-inhibit-predicate' that is used as
`electric-pair-inhibit-predicate' by cc-mode. Specifically this check
(not (equal (c-get-char-property last-quote 'c-fl-syn-tab) '(15)))
fails, because the macro
(c-get-char-property last-quote 'c-fl-syn-tab)
that expands to
(get-text-property last-quote 'c-fl-syn-tab)
where `last-quote' is the position of the last quotation mark in a
"logical line", evaluates to nil, not (15). I do not understand why
this happens, or what the text property `c-fl-syn-tab' is supposed to
indicate.
I have CC'ed Alan to see if he can help.

Hello, Philip.
Sorry I missed this bug in January.

The reason apostrophes don't work with electric-pair-mode is that they
are not quote characters in AWK. :-)

It happens because AWK Mode doesn't use the unterminated string
detection code the other CC Mode modes use. (It doesn't need to, being
simpler.) So, rather than temporarily storing its "working"
syntax-table text properties, AWK just lets them be. So, we can just
test the syntax-table text property for being '(15) (string fence) in
AWK Mode.

Would you please try out the following patch, and let me know how it
goes. Thanks!

Thanks for the testing! I've actually committed a somewhat different
patch to savannah master, which also fixes one or two other minor things
in the area. I'm also closing the bug with this post.
