[0.12.5] Lua TransportLine get_contents()

[Kikkers]

This scripting function doesn't seem to populate the table it returns.

Reproducable by filling a belt, calling get_contents() on one of the belt's lines, and printing the # of the returned table.

#table doesn't work that way for named indexes:


You have to check for the key and then if it isn't nil check the count it returns.

What a language, what a wonderful language.

You're completely right, but still, I was sure i did check whether looping worked. Apparently not.
