Thanks for the detailed report!

The config isn't failing to load, we just didn't support sendmailCmd, because
it only got introduced in later git versions. So far, we only recognized when
smtpServer was set to a path.

This is now fixed in master -- b4 now honours sendmailCmd with the same
precedence as git itself (it wins over smtpServer when both are set), so if
you pull the latest master, your existing configuration should work as-is,
without any changes.

If you'd rather stay on a release version until this ships, the
workaround is to use smtpserver, e.g:

    git config sendemail.private.smtpserver "$(which msmtp)"

Thanks again for the report and the thorough debugging output.
