It would be nice to have Appveyor failing due to the bug.

@gucong3000 Thanks! I don't have write access here but I'll look into your changes and it to my branch. (spawn wrap is being slowly phased out).

I started merging my fork into the main lib (#77, #78, and probably a few more in the upcoming days). I'll make sure to rebase your fix on top of it.

Any update here? This has been blocking me from using the 'nyc' code coverage package on Windows for months now.

Hi,
Here is an update of the situation:

The library got migrated from the tapjs org to istanbuljs to bring new maintainers. It is planned to release a new major version of spawn-wrap and address some of the long standing issues. You may have noticed a recent increase in activity, that's the reason.

Regarding this particular issue, we are looking into it and would like to address it. The fix looks simple but I am not a Windows expert, nor @coreyfarrell. This is probably why it is not merged already: we want to understand the impact of the PR and if there's a risk of breaking something. For example, I am worried about how it interacts witch cross-spawn and would like to test it before.

Also, thank you very much for the repro in #70 (comment), it helps greatly.
