* SUMMARY: Regression test for Bugzilla bug 100199
* See http://bugzilla.mozilla.org/show_bug.cgi?id=100199
*
* The empty character class [] is a valid RegExp construct: the condition
* that a given character belong to a set containing no characters. As such,
* it can never be met and is always FALSE. Similarly, [^] is a condition
* that matches any given character and is always TRUE.
*
* Neither one of these conditions should cause syntax errors in a RegExp.
