 * 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.
