[ Upstream commit 6ae0042f4d3f331e841495eb0a3d51598e593ec2 ] Subshell evaluations are not exempt from errexit, so if a command is not available, `which` will fail and exit the script as a whole. This causes the helpful error messages to not be printed if they are tacked on using a `$?` comparison. Resolve the issue by using chains of logical operators, which are not subject to the effects of errexit.
