contrib: restore the `hg fix` configuration in the examples
After decc3bd3f20d, running `black` will DTRT, but running `hg fix` did nothing
(unless the example config file was %included, in which case it truncated the
file instead of formatting it). I'm not sure why that was happening, but let's
not leave a code shredder laying around.
