disallow alternatives without elements

While (re-)writing long regular expressions, it can happen that one forgets to remove the | character of a former alternative. This rule tries to point out these potential mistakes by reporting all empty alternatives.

If the empty alternative is supposed to match the empty string, then use a quantifier instead. For example, a| should be written as a?.

Nothing.

This rule was taken from eslint-plugin-clean-regex.
This rule is compatible with clean-regex/no-empty-alternative rule.

This rule was introduced in eslint-plugin-regexp v0.8.0
