[issue31012] suggestion: allow termination argument in argparse to be specified as argument

[Leon Avery]

New submission from Leon Avery:

In the argparse module, the argument '--' is interpreted as a signal that 
everything after it is a positional argument. '--' is literally written into 
the argparse code, in _parse_known_args. This means that a user who wishes to 
use '--' in some other way is out of luck. 

I suggest the addition of an argument to __init__ (or a method call, or 
something) that allows '--' to be replaced with some string of the user's 
choice.

[issue31012] suggestion: allow termination argument in argparse to be specified as argument

[Leon Avery]

Leon Avery added the comment:

The POSIX guideline suggests that -- should be available as an option argument. 
One should be able to say "command --opt --" in order to make '--' the value of 
the '--opt' option. 

> There are some known problems with this '--', specially when there are more 
> than one.

Yes. That is exactly the problem I have.
