string.gmatch confusion

[Mitchell <lists@...>]

Hi,

I must be missing something:

> for i in string.gmatch('foobar', '.', 4) do print(i) end
f
o
o
b
a
r

I expect only the characters from 'bar' to be printed since I am passing the 'init' argument to string.gmatch.

What am I missing or not understanding?

Cheers,
Mitchell
