Well, you could compute n from what you know but that would imply creating a new regular expression for each iteration which is probably not what you want.
Can you confirm me that you see no other way of doing it? Right now in my code, I just do the full scan and throw the results away if the start was to far in the string. I've not tried compiling a new regex at each iteration but I guess it will be longer.
With the new filter facility you should be able to create a filter which checks the current position against some special variable, say *MAX-START*. You can set *MAX-START* accordingly before each scan but the regular expression will only be compiled once because it doesn't change. Something like that should work, shouldn't it?
