Yes, it does look better than all uppercase, so I'll accept.
(That I stuck to uppercase is because it wastes less space,
and with just 80 characters width this sometimes matters,
plus it seemed widespread tradition.)

The middle one would need the pointy brackets, too, no?
-o, --optional[=<arg>] this option has optional_argument

As a translator I do not quite like the separation of the
"\nUsage:\n" string from the actual synopsis -- it is good
to have some context in the string. But I'll accept. The
initial space of the actual synopsis strings will eventually
let translators understand what they are.

Especially the latter would be nice: at the moment there are
many such lines with just a differing final word.

That won't work -- the amount of indentation for the option description
is not the same for all utilities. And to make it the same for all would
create ugly and unneeded wide open text spaces for some tools.

Do you mean that you want to use "--option <argument>" also in the
man pages, Karel? Or do we stick there to italics for arguments?
(Which translates to underlining on terminals.)
