fix minor bug in make-dfa-loop.sml: when folding backwards using an if-statement, make sure we start folding from the leftStrings if the cursorIdx < 0

amend very minor bug: when looping through DFA and hitting a 'final state', we let the next chr afterwards handle the start state, but we want the current char to handle the start state instead, as this matches vim's behaviour

|
fix bugs in vi-l-dfa (we want to stop looping when the counter is ~1, because the starting character will likely be final/a not-newline, and we want to loop at least once; also, we want to special case 'twoNewlineState' as a final case which causes us to go backwards by 1 instead of treating 'oneNewlineState' as a final/special case). We also modify other code to use the new vi-l implementation in the program.
