Since d3f4628e (revert: Remove sequencer state when no commits are
pending, 2011-07-06), the sequencer removes the sequencer state before
the final commit is actually completed. This design is inherently
flawed, as it will not allow the user to abort the sequencer operation
at that stage. Instead, write and expose a new function to count the
number of commits left in the instruction sheet; use this in
builtin/commit.c to remove the sequencer state when a commit has
successfully completed and there is only one instruction left in the
sheet.
