   This indeed could work as an approach (I suggested /tmp, you are using a 
   single buffer to back up contents, but the effect should be the same).

Yup, a temp file would make it work for multiple files.

   Do you like the current behavior with Git, though? Or do you perhaps 
   have the same misgivings as Eli?

I've not tried Juri's change, but from the point of maintaining
vc-fossil it would mean that I need to figure out how to implement
this vc-checkin-patch function (and likewise for anyone else),
specially when there is no need to make this git specific for the most
common case.
