My request was not about stripping it, but making it useful. I don't
know the b4 patch sending side, but git send-email has the capability to
make it more useful in this scenario. I didn't check, but
`b4 --edit-deps` which Abel mentioned sounds about right.

The relevant documentation for the git side is the paragraph "BASE TREE
INFORMATION" in git-format-patch(1).

Best regards
