This does not seem to directly add MultiLineString support. Should we keep #2886 open or suggest people using multiple lines to achieve it?

[sissbruecker]

I did re-read both tickets today and came to the conclusion that there was a misunderstanding what the purpose of LineString / MultiLineString is. In the ticket for LineString it only mentions single lines with start and end point, while it actually also allows creating paths with multiple segments, which is described as use-case in the ticket for MultiLineString. As such I figured it's fine to close both tickets.

Maybe there would be a use case for adding multiple line strings at once using MultiLineString but that's a different use-case than what's described in the ticket.

LGTM.
