[PATCH v2 3/5] t4301: verify that merge-tree fails on missing blob objects

From
Johannes Schindelin via GitGitGadget <gitgitgadget@gmail.com>
Date

Message-ID
<be1dadf28502fe3e9662fa61523e8c57ce3352f1.1707324462.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.1651.v2.git.1707324461.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>

We just fixed a problem where `merge-tree` would not fail on missing tree objects. Let's ensure that that problem does not occur with blob objects (and won't, in the future, either).
