Removed "glob" from node pattern description

A glob is a pattern that supports * and ? wildcards. This is not
supported for node patterns. I'd call these "hostlist" patterns; but
easier to just leave it generic for now until and unless there is
documentation to refer to on the website about the pattern type.
