Docker at some point decided to stop creating stderr pipes when starting a process connected to a terminal. This patch adds some select logic to correctly support this new use case.
This problem manifests when using runv with docker versions >1.13 and possibly earlier.
This patch fixes the problem for all versions by ignoring the need to open stderr if a terminal is requested and the file does not exist. If it does exist, it is presumed the old behaviour is desired.
