`with` does not accept `OsStr`

[ccyuen1]

Currently OsStr and OsString are not accepted as the app parameter of with, with_command, with_detached, and with_in_background. This does not make sense to me because OsStr should be suitable for interacting with the OS.

I can see that changing app: impl Into<String> to app: impl AsRef<OsStr> or app: impl Into<OsString> is a breaking change. Is there a way to overcome this?

I don't think so, unless one would want to duplicate the API.

Instead, I'd probably just create a new breaking release.
