It cannot be resized manually.  It resizes itself when enough text is
added to it, and also when the font size is set etc.  However, there's
no reason it can't resize like the first four flowchart shapes.  Patches
would be welcome (and probably easy to make, given other objects do what
is wanted).

The center handle is the handle for the message text.  Unlike some other
connectors (like the FS flows), the message cannot be edited directly in
the diagram, which is an error.  As for why it's a straigt line rather
than a zig-zag line, that's a decision made by the UML sheet designers. 
Unfortunately, it isn't easy to switch a line from straight to zig-zag
at run-time.
