Maybe I should just leave the warning and let it continue. The reason
I added it was that "git-apply --index" fails if there is no diff.
In the meantime, you can try the attached patch for StGIT.
Another hint - quilt can apply patches with fuzz but GIT doesn't allow
this by default. If a patch fails, the diff is dumped to the
.stgit-failed.patch file so that you can apply it manually (with patch
or git-apply) and run 'stg refresh' afterwards.
After an import failure, you can continue importing from the next
patch using the 'stg import --ignore' option.

I'll give it a try.
One thing you'll notice is the speed difference as stgit has to
generate a git commit during a push operation.

We had the full name in the past but the algorithm cause problems with
patches (not e-mails) that didn't have a subject line. It's probably
better to have a config option rather than hard-coded 30 characters.
Note that 'stg series -d' will display the full subject line.
If you don't give up before importing the files :-), please let us
know the user experience, especially related to speed as compared to
quilt.
Karl, maybe it's worth trying this series with your DAG patches as well.
Regards.
