[Python-Dev] argparse ambiguity handling

[Neal Becker]

I've noticed argparse ambiguity handling has changed a bit over last few 
revisions.

I have cases where 1 valid input is a prefix of another:

e.g.:
'--string'
'--string2'

With the most recent 1.1, the behavior is:

--string=hello

is accepted, while:

--strin=hello

is marked as ambiguous.

I'm OK with this, but just want to know if there is agreement that this is 
the behavior we want.
