[PATCH 1/2] index-pack: clarify the breached limit

["Matt Cooper via GitGitGadget" <gitgitgadget@gmail.com>]

From: Matt Cooper <vtbassmatt@gmail.com>

As a small courtesy to users, report what limit was breached. This
is especially useful when a push exceeds a server-defined limit, since
the user is unlikely to have configured the limit (their host did).
