+*
+* SUMMARY: Testing regexps with the global flag set.
+* NOT every substring fitting the given pattern will be matched.
+* The parent string is CONSUMED as successive matches are found.
+*
+* From the ECMA-262 Final spec:
+* 
+* 15.10.6.2 RegExp.prototype.exec(string)
+* Performs a regular expression match of string against the regular
+* expression and returns an Array object containing the results of
+* the match, or null if the string did not match.
+*
+* The string ToString(string) is searched for an occurrence of the
+* regular expression pattern as follows:
+*
+* 1.  Let S be the value of ToString(string).
+* 2.  Let length be the length of S.
+* 3.  Let lastIndex be the value of the lastIndex property.
+* 4.  Let i be the value of ToInteger(lastIndex).
+* 5.  If the global property is false, let i = 0.
+* 6.  If I < 0 or I > length then set lastIndex to 0 and return null.
+* 7.  Call [[Match]], giving it the arguments S and i.
+*     If [[Match]] returned failure, go to step 8;
+*     otherwise let r be its State result and go to step 10.
+* 8.  Let i = i+1.
+* 9.  Go to step 6.
+* 10. Let e be r's endIndex value.
+* 11. If the global property is true, set lastIndex to e.
+*
+*          etc.
+*
+*
+* When the global flag is set, |lastIndex| is incremented every time
+* there is a match; not from i to i+1, but from i to "endIndex" e:
+*
+* e = (index of last input character matched so far by the pattern) + 1
+*
+* Thus in the example below, the first endIndex e occurs after the
+* first match 'a b'. The next match will begin AFTER this, and so
+* will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched.
