Subject: [man pages]: Revise some syntax synopses.

Use ellipsis more idiomatically, favoring it over plurals, and including
it within instead of outside option brackets for clarity.

The construction:

foo bar [baz] ...

is ambiguous.  If I specify no "baz", can "bar"s be repeated?

Also say "argument" when we mean an option OR an operand.
