annotate mercurial/stack.py @ 43075:57875cf423c9

style: run a patched black on a subset of mercurial

This applied black to the 20 smallest files in mercurial/:

    ls -S1 mercurial/*.py | tail -n20 | xargs black --skip-string-normalization

Note that a few files failed to format, presumably due to a bug in my
patch. The intent is to be able to compare results to D5064 with
https://github.com/python/black/pull/826 applied to black.

I skipped string normalization on this patch for clarity - in reality
I think we'd want one pass without string normalization, followed by
another to normalize strings (which is basically replacing ' with "
globally.)
