The set of errors forwarded by the os package varied with system and was therefore non-portable. Three helpers added for portable error checking: IsExist, IsNotExist, and IsPermission. One or two more may need to come, but let's keep the set very small to discourage thinking about errors that way. R=mikioh.mikioh, gustavo, r, rsc CC=golang-dev https://golang.org/cl/5672047
