I'd like to bundle this solution with mintty for the wsltty standalone 
package. I could bundle a patched version but I'd prefer an official 
release or at least test release for publishing.
I haven't seen this patch yet in the git repository, when will it be 
ready for cygwin 3.7.0?
Thanks,
Thomas
