A 40-byte hex representation of a SHA-1 or a name that denotes a
particular object. They may be stored in a file under $GIT_DIR/refs/
directory, or in the $GIT_DIR/packed-refs file.
Do master~3 and :/foomery qualify as refs?

When quuxery is a submodule, master:quuxery refers to a commit object
that does not exist in the parent repository. I don't know what we
gain by documenting a comittish you can't even `show`.
