REMAINDER is not widely used, and probably was not tested thoroughly during 
development. It works for the example given in the docs.  

A variant, argparse.PARSER ('A...') is widely used.  This is, effectively, 
REMAINDER ('...') that requires an initial non-optional string.  Sort of what 
'+' is to '*'.

I suspect REMAINDER is most reliable when used as nargs for an optional, e.g.

    add_argument('--rest', nargs=argparse.REMAINDER)

That way it's clear to everyone, developer, user, and the parser that the 
following strings are to be taken is.  

When parsing the command line, clarity should have priority over convenience.
