Yeah, that would be annoying to run into.  Rearranging the description
a little for clarity and brevity:

	fast-import: update refs on checkpoint even if there are no new objects

	During an import using the fast-import command, it is possible for
	no new objects to have been added between two checkpoints requested
	with the SIGUSR1 signal or the "checkpoint" command.  Even in this
	case, fast-import should write out any updated refs and marks to
	fulfill the second checkpoint request.

	As before, fast-import will not write an empty pack and start a new
	one when there are no new objects to write out.

With that change,
