bug#23295: 24.5; in cc-mode, '(' replaces selection with '(' when electric-pair-mode and cua-mode are active

[a.c.kalker]

When editing a C source file while cua-mode and electric-pair-mode are
both active, typing '(' replaces selected text with '(' instead of
wrapping it in '(' and ')'.

Steps to reproduce (in `emacs -Q`):
- C-x C-f foo.c RET
- M-x cua-mode RET
- M-x electric-pair-mode RET
- Type: #define FOO(x) x + 42
- Select "x + 42"
- Type: (

Expected result:
- Text should read: #define FOO(x) (x + 42)

Actual result:
- Text reads: #define FOO(x) (

Remarks:
- Turning off cua-mode, marking the selection with C-SPC and movement
keys, then typing '(' works as expected.
- The problem appears to only occur in cc-mode.

Hello.

Thanks for taking the trouble to submit this bug report to Emacs, and
apologies that it has taken so long for us to respond.

The bug you reported seems to have been fixed at some time in the last
few years.  I cannot reproduce it anymore.  So I'm closing it as "won't
fix", since no more action is required.
