Re: [PATCH v2] refs: make rev-parse --quiet actually quiet

David Aguilar [off-list ref] writes:

When a reflog is deleted, e.g. when "git stash" clears its stashes,
"git rev-parse --verify --quiet" dies:

	fatal: Log for refs/stash is empty.

The reason is that the get_sha1() code path does not allow us
to suppress this message.

Pass the flags bitfield through get_sha1_with_context() so that
read_ref_at() can suppress the message.

Use get_sha1_with_context1() instead of get_sha1() in rev-parse
so that the --quiet flag is honored.

This is a replacement patch for "refs: make rev-parse --quiet actually quiet"
from da/rev-parse-verify-quiet in pu.

Looks good; thanks.
