Bug 1416052 - Remove comment filtering; r=nalexander The auto-generated make file that we include (and the `mach environment` output that we included before that) should not contain comment lines. I think it is safe to remove the code that filters them out. It is possible a multi-line value in mozconfigs could contain lines looking like comments and this may cause problems. I'm inclined to believe that this scenario doesn't exist. If someone complains and we need to bring back support, we could certainly do that. MozReview-Commit-ID: 8kKw91HH4ms
