maybe unused global (pts)

[H]

I saw that in mouse_smoothly_to_pos and wondered if pts is used anywhere outside the function.

I used $ ag -rl pts scripting/ but I didn't find a use of it.
Maybe it could be localized (like in line 133).

If you want to get informed about undeclared globals, I think you could use that code

Thanks for pointing out the issue and linking to the code. We definitely need some Lua checking tools - see also https://bugs.launchpad.net/widelands/+bug/1385831
