Strictly speaking a safe "read" would be IFS= read -r line (IFS= to avoid 
stripping leading whitespace, -r to avoid backslash escapes being 
processed).  However, in this case that's not needed because valid test 
result lines do not start with whitespace and do not contain backslash 
(and nor do they start -n or -e, being cases where the "echo" would be 
unsafe).
