Initial messing around....
Initial messing around. Latex tab completion will have to be done outside the normal completer logic as the completer line splitting logic uses \\ as a special character to split lines on. I probably want to put the latex completions first and it if finds any matches, don't do any other completion logic. The only issue is that might short circuit dir/path matching on windows. Hmmm.
