Compile and use:

# Be sure it's at least Rust 1.26 
cargo build --release

Now run it like this:

echo dc595f7f016a0cff8b176a4c1e67483986f14816 | git-commits-by-blobs <path-to-repo>

Pipe one hex-sha per line to stdin, and get space-separated hex-shas of all commits that use them, followed by newline.

• it only reads commits reachable from the HEAD of the repository. This can easily be fixed by adding more targets to the Revwalk instance.
