While sending patches, it took me time to realize that it was not just
the format-patch --thread documentation being inaccurate, but that the
interactions with send-email were not obvious - and that the config
items specific to send-email were not at all described in the central
config.txt.

Now that bizarre interaction may just be due to a bug that we'd like
to fix instead ?

Yann Dirson (2):
  List send-email config options in config.txt.
  Improve doc for format-patch threading options.
