[plt-scheme] Question on plt-match.ss (typo?)

Hi all,

What's the difference between ..k and __k in ooo?
I did try some examples but they do seem to be equal. Doesn't
make sense to me but the manual really says "k or more, where k
is a non-negative integer" for both.

Could someone clarify this to me?

I found this issue while trying to find a way to say "match
this pattern 0 or 1 time".


Cheers,
