`radicle-term` includes quite a lot of rather "low-level" logic to spawn
the preferred editor of the user. In particular, this logic is
platform-dependent and only works on Unix-like platforms.
Also, `radicle-term` already depends on `inquire` which features an
editor prompt. It is a cross-platform solution to spawn the editor.
This commit changes the implementation of `Editor` to be a wrapper of
`inquire::Editor`, keeping the interface mostly intact.
Downsides:
- We cannot edit a file "in place" this way, instead we have to read
it, as `inquire` only supports editing temporary files. This can also
be viewed as a benefit, as we lessen the risk of corruption of these
files.
- `inquire::Editor` contains borrows, so it is quite cumbersome to
extend it with a custom mechanism for looking up the preferred
editor. The lookup logic was kept, but needs to be invoked by the
caller. In the future we might consider just using the logic provided
by `inquire` or requesting a change to `inquire`.
- The prompt is a bit strange. It does not show the current state of
the output, see <https://github.com/mikaelmello/inquire/issues/280>
and <https://github.com/mikaelmello/inquire/pull/271>.
