aaf6fc0982 bpo-26510: make argparse subparsers required by default (#3027) 
This fixes a regression from Python 2.  To get optional subparsers,
use the new parameter ``add_subparsers(required=False)``.

0f6b9d2306 bpo-14191 Add parse_intermixed_args. (#3319) 
This adds support for parsing a command line where options and positionals are intermixed as is common in many unix commands. This is paul.j3's patch with a few tweaks.

841b930a41 Issue #17940: Remove redundant code from _Section.format_help() 
Output of func(*args) stored in the next line:

    item_help = join([func(*args) for func, args in self.items])

_Section.items only used by HelpFormatter._add_item() and it looks
like it doesn't have any side effects.

7570cbdc6b #9351: set_defaults on subparser is no longer ignored if set on parent. 
Before, if a default was set on the parent parser, any default for that
variable set via set_defaults on a subparser would be ignored.  Now
the subparser set_defaults is honored.

eaae1b76ae A follow up for issue #15906: change the test for calling the type conversion 
on the action's default, reverting it back to previous behavior.  Conversion
is only done on string defaults.

Add a test for this and another test that ensures such type conversions are
only called once.

63755f3bd9 merge #15847: allow args to be a tuple in parse_args 
This fixes a regression introduced by the fix for issue #13922.  Although args
is not documented as being allowed to be a tuple, previously this worked and
so naturally there are programs in the field that depend on it.

64b0ef1509 Merge #12776,#11839: call argparse type function only once. 
Before, the type function was called twice in the case where the default
was specified and the argument was given as well.  This was especially
problematic for the FileType type, as a default file would always be
opened, even if a file argument was specified on the command line.

Patch by Arnaud Fontaine, with additional test by Mike Meyer.
