Unix usage

Many Unix programs have abandoned the brevity of the Unix usage summary. When mistyping a command:

$ foo
usage: foo [options] args

[options] is nearly useless. As is this:

$ more
more: bad usage
Try 'more --help' for more information.

Here's what the util-linux package's more command usage summary should look like:

$ more
usage: more [-cdflpsuV] [+linenum | +/regex] file [...]

If further description is needed, that's what the man page is for, (or something similar to the Windows help command, or GNU --help).
