This crate is not a library, i.e., it is not intended to be depended
upon by other crates. Rather, it implements the `git-remote-rad`
binary.
Reflect this by moving `lib.rs` to `main.rs`, merging it with
`git-remote-rad.rs`.
The `verbosity` option is ignored, which makes it more difficult to
obtain debugging information if the "internal" push, i.e., the
`git push` invocation by `git-remote-rad` fails.
Provide two types for verbosity, and wire them up.
Microsoft Windows has Universal Naming Convention (UNC) paths, see
<https://learn.microsoft.com/en-us/dotnet/standard/io/file-path-formats#unc-paths>
The Rust standard library normalizes paths to this form when calling
`std::fs::canonicalize`, see
<https://doc.rust-lang.org/std/fs/fn.canonicalize.html>
However, some programs, do not parse these paths correctly, including
our ally `git`:
$ git clone \\?\C:\Users\lorenz\tmp
Cloning into 'tmp'...
ssh: Could not resolve hostname \\\\?\\c: No such host is known.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
The `dunce` crate solves the problem of having to deal with
normalization and avoiding weird UNC paths for us. Note that on
non-Windows platforms, it *behaves exactly like*
`std::fs::canonicalize`!
Introducing the new enum `TerminalFile` to model which standard stream
stream the terminal uses allows us to remove the dependency on `libc`
which does not build on Windows.
