From: Adam Johnson <me@xxxxxxxx>
"git stash --staged" would crash with binary files, after saving the stash.
This behaviour dates back to the addition of the feature in 41a28eb6c1
(stash: implement '--staged' option for 'push' and 'save', 2021-10-18).
Adding the "--binary" option of "diff-tree" fixes this. The "diff-tree" call
in stash_patch() also omits "--binary", but that is fine since binary files
cannot be selected interactively.
