Code Inspection: Empty branch in alternation

Reports empty branches in a RegExp alternation. An empty branch will only match the empty string, and in most cases that is not what is desired. This inspection will not report a single empty branch at the start or the end of an alternation.

Example:

(alpha||bravo)


After the quick-fix is applied:
(alpha|bravo)
