           Summary: std.algorithm.move only operates on hasLvalueElements

The call to "move" is smart, but pre-supposes the range has Lvalue elements.
remove should be able to work just fine for encapsulating ranges such as
container's.

Just a bit of change in the doc, and sparkle a few static ifs in the
implementation.
