I thought I clearly explained the logistics in a previous mail:

One of the problems with your approaches is that the commit IDs for
the patches I'm carrying become different from the commit IDs which
will end up being merged, which then means I have to either silently
drop _my_ commits and hope that they've been merged intact, or I have
to manually diff each patch and compare it with what's merged, or
I have to rebase my patch set on top of what's merged and hope that
git spots that the patches are already applied (which it won't do if
there's other changes on top of them which make it non-obvious to git
that they're applied.)

To put it another way, recommitting these changes makes /more/ work
for me in the long run because of how git works.
