I noticed this spacing in the --help output of 'who' that looked a bit
strange:
$ who --help
Usage: who [OPTION]... [ FILE | ARG1 ARG2 ]
Removing the spaces looks better, e.g., like this:
$ who --help
Usage: who [OPTION]... [FILE | ARG1 ARG2]
But I couldn't find any examples of a single argument or multiple
arguments combined like that. This looks more like what I expect, but
I'm not 100% sure about it, so I haven't pushed:
$ who --help
Usage: who [OPTION]... [FILE]
or: who [OPTION]... [ARG1 ARG2]

* src/who.c (usage): Use two lines. Remove the extra spaces between the
argument and brackets.
