Oh, then the output format would, just like "grep" given more than one
file tells which file it found the match in, talk about which path the
output entry talks about when given more than one path.

Something like:

	$ git check-ignore foo/bar xyzzy~ hello.c
	foo/bar: foo/.gitignore:4: ??r
        xyzzy~: .git/info/excludes:22: *~

that says "foo/bar is ignored because line 4 of foo/.gitignore tells us to
ignore any three-letter filename that ends with r, xyzzy~ is ignored
because .git/info/excludes tells us to ignore everything that ends with
tilde on line 22, and hello.c is not ignored at all."
