Junio C Hamano 9f0be82123 t1506: rev-parse A..B and A...B
Because these constructs can be used to parse user input to be
passed to rev-list --objects, e.g.

	range=$(git rev-parse v1.0..v2.0) &&
	git rev-list --objects $range | git pack-objects --stdin

the endpoints (v1.0 and v2.0 in the example) are shown without
peeling them to underlying commits, even when they are annotated
tags.  Make sure it stays that way.

While at it, ensure "rev-parse A...B" also keeps the endpoints A and
B unpeeled, even though the negative side (i.e. the merge-base
between A and B) has to become a commit.
