[PATCH] Dereference tag repeatedly until we get a non-tag.
When we allow a tag object in place of a commit object, we only dereferenced the given tag once, which causes a tag that points at a tag that points at a commit to be rejected. Instead, dereference tag repeatedly until we get a non-tag. This patch makes change to two functions: - commit.c::lookup_commit_reference() is used by merge-base, rev-tree and rev-parse to convert user supplied SHA1 to that of a commit. - rev-list uses its own get_commit_reference() to do the same. Dereferencing tags this way helps both of these uses. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
