Running zless with no arguments returns 'usage: zmore files...'. Should be 'usage: zless files...' Reproducible: Always Steps to Reproduce:
I sent this upstream http://lists.gnu.org/archive/html/bug-gnu-utils/2004-06/msg00082.html It's pretty much fixed now. Running zless returns Missing filename ("less --help" for help) Not sure if my bug report had anything to do the the change.
