[issue14174] argparse.REMAINDER fails to parse remainder correctly

paul j3 added the comment: Here's a possible solution to the problem (assuming there really is one): - redefine REMAINDER so it matches a '((?:A[AO]*)?)' pattern (where O is a string that looks like an optional flag, A an argument string). I've added the condition that the first match (if any

paul j3 added the comment: By the way, parser.parse_args() uses parse_known_arg(). parse_known_args returns a Namespace and a list of unknown arguments. If that list is empty, parse_args returns the Namespace. If the list is not empty, parse_args raises an error. So parse_known_args does n

[issue14174] argparse.REMAINDER fails to parse remainder correctly

New submission from Arnout van Meer : Reproduction case is attached and should speak for itself, but the short brief is that the argparse.REMAINDER behaviour is very inconsistent based on what (potentially) defined argument handlers come before it. Tested this on Python 2.7 on OS X, but also g
