[New-bugs-announce] [issue19814] Document prefix matching behavior of argparse, particularly for parse_known_args

[Eli Bendersky]

New submission from Eli Bendersky:

Prefix matching behavior can lead to bugs when combined with parse_known_args. See this thread for more details:

https://mail.python.org/pipermail/python-dev/2013-November/130601.html

Issue #14910 deals with making it optional, but until 3.5 we'll have to do with a documentation warning.
