Subject: [PATCH v2 09/10] hash-object: show usage on invalid --type
Date: Tue, 20 Apr 2021 15:00:15 +0200
Message-ID: <patch-09.10-eaa1b8f44c-20210420T125416Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-00.10-0000000000-20210420T125415Z-avarab@gmail.com>

Change the error displayed on "hash-object -t bogus" (without
--literally) to show the usage_with_options(), like we do for the
other usage errors.

As noted in a preceding commit it makes sense to pass the "len" down
to the object.c code, so now that we're using
type_from_string_gently() let's do that.
