The ellipsis is a grammar metacharacter, just like the []()|.
Write *FOO*… instead of *FOO…*, so the ellipsis is not underlined
in the man page. Not super sure about this one.
This matches the style in man(1) (except that we use the … ligature).
A previous iteration did the reverse (never use a space before the
ellipsis). That would be a smaller change.
For alteration we usually use "(a | b)", not "{a | b}".
While at it, instead of writing 4/6 subcommands in one line, write them
on separate lines, so it's very obvious that all these are separate
subcommands. We mainly use the (a | b) syntax for long/short options.
