rhg: make output of `files` relative to the current directory and the root
This matches the behavior of `hg files`.
The util is added in `hg-core` instead of `rhg` because this operation could
be useful for other external tools. (this was definitely not prompted by rust
issue #50784, I swear)

//! A distinction is made between operations and commands.
//! An operation is what can be done whereas a command is what is exposed by
//! the cli. A single command can use several operations to achieve its goal.

// TODO add an `Operation` trait when GAT have landed (rust #44265):
// there is no way to currently define a trait which can both return
// references to `self` and to passed data, which is what we would need.
// Generic Associated Types may fix this and allow us to have a unified
// interface.
