Current regex produces insane result.
$ ./python -c import textwrap; print(textwrap.wrap('this-is-a-useful-feature',
width=1, break_long_words=False))
['this-', 'is-a', '-useful-', 'feature']
Antoine's regex produces more correct result for this case:
Antoine Pitrou added the comment:
But this is not totally correct, one-letter word should not be
separated.
Why not? I guess it depends on English's rules for word splitting, which I
don't know.
In any case, this issue is not about improving correctness, only performance.

I suppose this is common rule in many languages. And current code supports it
(there is a special code in the regex to ensure this rule).

I frankly don't know about this rule. And the tests don't check for it, so for
me it's not broken.

This is related to the fix for issue 14432. gen_send_ex sets f-f_tstate to
NULL, so PyFrame_IsRestricted segfaults:

If you import a module that creates a multiprocessing.Queue, puts a value, and
then waits for to be received again from the queue, you run into a deadlock.
The issue is that Queue._feed does 'from .util import is_existing' - which

The current wording of the passage “Match objects always have a boolean value

You are talking about time.strftime, I presume. datetime supports %f.
time.strftime does not, because it wraps the system strftime, and that does not

A notational point - you are adding a subparser, not an argument, to the
subparsers action.
Why would a user want to use `help=argparse.SUPPRESS`, as opposed to simply
omitting the `help` parameter? The effect would be the same as your patch.
