[PATCH] t5500: prettify non-commit tag tests

[Jeff King <peff@peff.net>]

We don't need to use backslash continuation, as the "&&"
already provides continuation (and happily soaks up empty
lines between commands).

We can also expand the multi-line printf into a
here-document, which lets us use line breaks more naturally
(and avoids another continuation that required us to break
the natural indentation).

I had prepared this as a squash-in for what became c12c9df527, but since
that's now in master, it can go on top (or get dropped, but I think it
is worth it as a style fixup).
