* bug#20425: 24.5; completion-at-point not working with prefix starting with '(:'

The issue can best be demonstrated as follows:

* Start vanilla emacs via emacs -q
* Switch to scratch buffer
* Enter the string '(:backg'
* Toggle completion-at-point (using C-M-i and M-x makes no difference)
* emacs will incorrectly report that no matches have been found

What should happen is that the prefix is completed to ':background'.
Removing the open paren and trying to complete with ':backg' as prefix
leads to the correct behaviour.

The above is just a specific example. In general completion-at-point is
not correctly completing for all of emacs' keywords which start with a
colon if the colon is preceded by '('.
