Oh. The point of this is that the arguments (operands in this case)
remain whitespace-delimited, where it might not be the case for a
repeatable single-letter option.
foobar [-adX] [-v...] file ...
foobar [-h | --help]
-v... Be more verbose. The option letter can be repeated, increasing
the verbosity level.
"[-v ...]" would imply that only "-v -v -v" is allowed, instead of
"-vvv".
I think this is a matter of achieving an accurate and unambiguous
synopsis grammar.

Branden
