I agree that the original names are ambiguous. query_refspecs_multiple()
is similar to query_refspecs(), but instead of returning the first match, it
collects all matching results.

To improve clarity and consistency, I’d like to propose the following
renames:
    *query_refspecs() -> find_refspec_match()
        `find` better describes its purpose than `query` and `match`
        clarifies that it’s looking for a single result.

    *query_refspecs_multiple() -> find_all_refspec_matches()
        Unlike the previous function, this one collects all matching results
        instead of stopping at the first match. The new name highlights that
        it returns multiple matches.
Let me know what you think!
