[issue7132] Regexp: capturing groups in repetitions

[Philippe Verdy]

Philippe Verdy <verdy_p at wanadoo.fr> added the comment:

Implementation details:

Currently, the capturing groups behave quite randomly in the values returned by MachedObject, when backtracking occurs in a repetition. This 
proposal will help fix the behavior, because it will also be much easier 
to backtrack cleanly, occurence by occurence, by just dropping the last 
element in the list of (start,end) pairs stored in the MatchedObject for 
all capturing groups specified WITHIN the repeated sub-expression.
