And the result is a pleasing diffstat.

Subject: commit.c: remove print_commit_list()

The helper function tries to offer a way to conveniently show the last one differently from others, presumably to allow you to say something like

	A, B, and C.
while iterating over a list that has these three elements.

However, there is only one caller, and it passes the same format string "%s\n" for both the last one and the other ones. Retire the helper function and update the caller with a simplified version.
