Cute.

In a case like this, I tend to just do:

    git checkout $(git merge-base master js/series)

    git format-patch --stdout master..js/series | git am -s

    git diff js/series
    git branch --with js/series
    git branch -f js/series

as the first step (checking out the base, detaching HEAD) and the last group of steps (verifying what improvements I made while on detached HEAD, checking what _other_ branches may need to be rebuilt, and actually updating the branch) are very common for my every-day branch whipping workflow, and the second case being the full "format-patch | am" is just a special case of what I do regularly, e.g. cherry-picking, manually fixing-up, etc.

Rebase -i is very nice if you need to dig deep but the change you make is actually very limited. Filter-branch is too automated and requires an enormous amount of effort to do anything flexible. Often I find myself wanting to do something in the middle, and I end up doing the "detach at the base and rebuild" procedure.

Will apply.  The hint is useful nevertheless.
