manual option --inline --no-attach override required for format.attach

[Brian Inglis <Brian.Inglis@Shaw.ca>]

What did you do before the bug happened? (Steps to reproduce your issue)
git format-patch --inline ... --to=linux-man@vger.kernel.org
git format-patch --no-attach ... --to=linux-man@vger.kernel.org
git send-email ... --to=linux-man@vger.kernel.org

What did you expect to happen? (Expected behavior)
linux-man maintainer would get patches inline not in attachments as expected

What happened instead? (Actual behavior)
linux-man maintainer got patches in MIME attachments which he could not use

What's different between what you expected and what actually happened?
using format-patch either --inline or --no-attach would send patches inline
need to remember to specify format-patch --inline --no-attach for every patch
there is no way to set config format.inline format.attach=no

Anything else you want to add:
initially found format.attach set in /etc/gitconfig and no way to override
would be great if linux-man maintainer could set repo config format.inline format.attach=no
