Prompt function with Write-Host on MacOS 10.12.5

See original GitHub issue

Steps to reproduce

When overwriting the prompt function as follows:

function prompt {
    Write-Host "Something> "
    " "
}

The reason why one would want to manually use Write-Host for outputting prompt values, is to be able to use colors. This is done in posh-git for example. In windows this works as expected.

Expected behavior

Something> --input goes here--

Actual behavior

Something>
 Something>
--cursor position--

When i start typing the input appears as follows:

Something>
--input appears here--

FWIW, on beta.3 this is still an issue. This shows up on Terminal.app and iterm2 with just PSReadline and the example prompt in this issue. Things are resolved if PSReadline module is removed, but all history, tab completing, etc functionality is gone (obviously).

Ah, ok… I missed the initial PSReadline reference - thanks 😃
