Subject: [PATCH] git-cat-file: '-s' to find out object size.
X-Git-Tag: v0.99~145
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=62bb99606d0377fc14f206cbdf95acb57149d87a;p=git.git

[PATCH] git-cat-file: '-s' to find out object size.

We use sha1_object_info() now, and getting size is also trivial.

I admit that this is more of "because we can" not "because I see
immediate need for it", though.
