pyproject: narrow the range of files processed by `black` I initially started looking at this, hoping to coax `hg fix` to read this, so it doesn't require manually setting something in `.hg/hgrc`. Also I noticed that it takes ~30s to run `hg fix` on a commit that is only adding all of the `*.pyi` files generated by pytype. That seems to be an issue with the extension itself, as updating the `exclude` list here didn't have much affect on the time it takes. That said, a simple command line run of `black`, which is what d4c8b4b90ecb was trying to allow, was reformatting the `cext/*.pyi` files, which seems undesirable. So we kill that off by including only `*.py` files, and also throw a few directories into the `exclude` list that are in my local `hg st -i` list, because we never want to process them. This saves a few seconds running `black` on the command line.
