It is indeed. Here is how I tested it, after pulling the latest master.

    - hg revert -r  a2dd9d683a02 (git hash), xterm.c and xfns.c are changed (reverted to that change set)

    - vc-dir

    - vc-diff

    - delete the first 2 hunks in xterm.c and then in xfns.c

    - vc-next-action

    - write a message

    - commit: commit took 10 sec!!,

    - I did the same step with the perl script commit-patch: 14 sec

So that looks indeed much faster! Thanks a lot 

Can somebody else please test this?
