The | suggests either one or another value, and that is what it is doing on the other options. finobt=0|1 ... rmapbt=0|1 ... etc. Same applies here: Either you use: sunit=value,swidth=value OR su=num,sw=num. The -l option has the same principle: -l ... sunit=value|su=num You either use sunit=value OR su=num.
