What
For big sets of paths, sync runs ls-tree and ls-files once over the whole tree and index rather than once per chunk of paths. If the output overflows the read buffer, that repository is remembered and sync falls back to the old chunked calls.
Details
Chunked calls now pin core.precomposeunicode=false so path bytes compare consistently across platforms.
Evidence
core.precomposeunicode=false
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
