But, it seems to me it'd be better to keep it explicit, so that it
doesn't interact poorly with other BufWrite* autocmds that other plugins
might use.

Also, you should add:

/e

to the end of each autocmd, for the unusual case that no lines in the
.py file are indented. (If you just started a new file, for example.)
Other than that, it seems to work for me on some simple files.
