commit d695f7b4235bb1a54658e5a5ba2f7ce025ffda92 Author: Sebastian Hahn <sebastian@torproject.org> Date: Fri Feb 6 21:53:22 2015 +0100 Don't use invalid exit values in zero length key test Shell exit values must fall into the range of [0-255], so let's honour this. In practice, the "exit -1" from the old code set an exit value of 255 on most systems, so let's pick that. Fixes part of bug #14478, patch idea suggested by an anonymous contributor.
