Re: [PATCH 14/22] test-lib functions: add --author support to test_commit

Add support for --author to "test_commit". This will simplify some
current and future tests, one of those is being changed here.

Let's also line-wrap the "git commit" command invocation to make diffs
that add subsequent options easier to add, as they'll only need to add
a new option line.

Makes sense.

-	git commit -m "Initial Commit" --author Frigate\ \<flying@over.world\> &&
-	git tag Initial &&
+	test_commit --author Frigate\ \<flying@over.world\> \
+		"Initial Commit" foo Initial Initial &&

Why not fix the value of the author while at it to be more readable?
E.g. --author "Frigate [off-list ref]"
