Andy, Axel, Is this what you expect?
:set cpo+=M

'( \(a[cursor_here]bc) )' -> dib -> '( \() )'

Here is a simple but ugly fix:

diff --git a/src/search.c b/src/search.c
--- a/src/search.c
+++ b/src/search.c
@@ -3637,7 +3637,10 @@
* Ignore quotes here.
*/
save_cpo = p_cpo;
- p_cpo = (char_u *)"%";
+ if (vim_strchr(p_cpo, CPO_MATCHBSL) != NULL)
+ p_cpo = (char_u *)"%M";
+ else
+ p_cpo = (char_u *)"%";
while (count-- > 0)
{
if ((pos = findmatch(NULL, what)) == NULL)


It will however always consider parenthesis in quotes, since '%' is
always included in 'cpo'

Be sure, to disable the matchit plugin, since it doesn't take the 'cpo'
settings into account.

See :h cpo-%
