The `shwordsplit` option affects all variables and we only need to split
the `$EDITOR` variable. Because of that, using `${=spec}` is a much better
alternative.

- Use `emulate -L zsh` to make all variables local.

- Use `shwordsplit` to interpret `$cmd` spaces correctly.

- Rename `$project` and `$file` variables to the more appropriate `$basedir`
  and `$project`.

- `$PROJECT_PATHS/*` wasn't working correctly. You have to iterate over
  its elements in order to use globbing with it.

- The `$projects:t` line wasn't necessary if we used `compadd`.

- `compadd` better supports destructuring an array with spaces in some
  of its elements.
