* Fixes the forgotton `[0]` found by leper that introduces a bug when parsing `<=` or `=>` (nasty bug because it's not triggered for DE, TM, Vox Populi,and other mods and because it's not directly obvious from reading the code`.
* Fixes the `warn` and forgotton regex argument of `split` I noticed once before and once after the commit.
