This does not:

1 3
I expect it to match the string at the index I passed to it, not
silently reposition the start at a valid index (1).
All the string functions do that. It is documented under string.sub.

Yes :-) I believe it makes sense for string.sub(), as you would want
the valid portion of the string from (let's say) -31 to 5. This would
be readjusted to only "sub out" indexes 1 through 5. I do not believe
it makes sense for string.find()/string.match() -- as false-positives
are possible when I tell it to match somewhere clearly before the
string (in a place it doesn't exist).
