Somebody in the thread at some point said:
| Let's fix simple warnings first.
|
| PS: I need a git-send-email hint. How do you use it?
|
| I used it like this and the subject doesn't change.
|
|     git-send-email -no-chain-reply-to \
|      --compose --suppress-from \
|     --smtp-server /usr/bin/msmtp \
|     --to "openmoko-kernel at lists.openmoko.org" \
|     --cc "" 00*.patch

I don't use it, there is stg mail command inside stgit that takes care
of it (you give it a list of patch names as arguments).
