handle edge case when deleting by DFA: when we are deleting to the end of the file and if cursor is on first character after newline, then we also want to delete preceding newline too. Or else we will end up with two newlines at the end of the file, which is not what we want.

fix minor bug regarding 'NormalMove.moveCursorDown': after a <count-j> that moved the cursor to the last line in the buffer, the cursor would be at the last column too, even if that wasn't the previous column. To address this issue, we take out code that calculates the lineIdx from the 'NormalMove.finishMoveCursorUpDown' function, and have both 'NormalMove.moveCursorUp' and 'NormalMove.moveCursorDown' calculate their own lineIdx in different ways and pass it to the 'NormalMove.finishMoveCursorUpAndDown' function.

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.
