I'm puzzled over the behavior of --first-parent. The documentations seems to imply
that only the first parent is followed, but when a filter is applied it seems (just guessing)
that the "first" parent is selected *after* filtering, a behaviour that I feel does not match
the documentation.

Should the first-parent filter be applied first.

Example:

	git log --first-parent --pretty=format: --name-only v1.5.2|grep ^var.c|wc -l

counts four commits where var.c was changed, while

	git log --first-parent --pretty=format: --name-only v1.5.2 -- var.c |wc -l

gives me 23.
