These should really have tests for the new types, but I've been using
them heavily for a few weeks and they work well. I would rather get them
committed now and add tests later.

Tested x86_64-linux. Pushed to trunk.

libstdc++-v3/ChangeLog:

	* python/libstdcxx/v6/printers.py (StdChronoDurationPrinter)
	(StdChronoTimePointPrinter, StdChronoZonedTimePrinter)
	(StdChronoCalendarPrinter, StdChronoTimeZonePrinter)
	(StdChronoLeapSecondPrinter, StdChronoTzdbPrinter)
	(StdChronoTimeZoneRulePrinter): New printers.

I ran a Python linter on the libstdc++ pretty-printers.

I have fixes for most of the issues that are worth fixing (I didn't
bother with line lengths -- FWIW in gdb we just run 'black' and don't
worry about these details), but the patch I'm replying to had a problem
that I didn't know how to fix:

flake8 points out that this call to format has three placeholders but
only two arguments.

I used autopep8 and committed the result as
e08559271b2d797f658579ac8610dbf5e58bcfd8 so the line lengths should be
OK now.

Oops, I think it was originally written like this:

'{} {}{}'.format(month, day, suffixes.get(day, 'th'))

but then I refactored it to:

ordinal_day = '{}{}'.format(day, suffixes.get(day, 'th'))
if kind == 0:  # DayOfMonth
            start = '{} {}{}'.format(month, ordinal_day)

So the fix is to just change the string to '{} {}' which I've pushed
as 1fab05a885a308c19cf42b72fd36805ddf27fdc8 now (also attached).

These printers are for implementation details internal to the library,
which are never exposed to users. I added them because they made it
much easier to debug the implementation when stepping through library
functions, but that means there are no tests for them.

Thanks for finding this!

Yeah, my patches are on top of that, but flake8 still complains, and I
still see lines > 79 characters.  However maybe flake8 isn't the checker
you want to use, or maybe you have something set up for a different line
length?

Thank you.

I don't think I have anything set up for python formatting at all, I just
committed whatever autopep8 did with its default settings.

If that's suboptimal, we can consider other tools, if they're reliable and
easy to run.

It looks like adding the -a flag would have made more changes.

The changes made by black seem reasonable, though I prefer it with -S to
disable string-normalization. It also needs an option to use 79 as the
maximum line length.

I've got some patches I'm about to send.

I made a pyproject.toml to auto-configure black (and isort), and this
works fine, but it also makes a bunch of edits.  So I'd rather send that
separately, after the current batch of patches is handled.

flake8 still isn't really happy, I guess because there are strings that
cause lines over 79, and black doesn't split those.  But meh, maybe
suppressing some flake8 errors is the way to go.

I was about to push some changes to split those strings up.
