Looking for findSplit?

Cool, that's what I want!
Now if I could find the elegant way to remove exactly one line from
the text without scanning the text after it...
Isn't that exactly what findSplit does? It doesn't have to search the
rest of the string after the match, it just returns a slice of the
rest of the array (I guess - haven't read the code)
import std.stdio, std.algorithm;
void main() {
auto text = "1\n2\n3\n4";
auto res = text.findSplit("\n");
auto pre = res[0];
assert(pre.ptr == text.ptr); // no copy for pre match
auto match = res[1];
assert(match.ptr == &text[1]); // no copy for needle
auto post = res[2];
assert(post.ptr == &text[2]); // no copy for post match
assert(post.length == 5);
}
Close... the reason findSplit doesn't work is because a new line could
be "\n" or it could be "\r\n" or it could be "\r".
