Description of Problem:
The Nautilus help says that to move a file, I can
just drag it from its old location to its new
location; however, if the two locations are on
different filesystems, Nautilus will default to
copying the file rather than moving it.

Steps to reproduce the problem:
(using nautilus-2.4.1 and gnome2-user-docs-2.4.1)
1. Examine section 1.4.3 of the Nautilus help.
2. Attempt to drag a file from one filesystem to
another without pressing any modifier keys, as it
says to do.

Actual Results:
The mouse pointer indicates that Nautilus will cop
y the dragged file rather than moving it, and it
does indeed copy it.

Expected Results:
The mouse pointer should indicate that Nautilus
will move the file, as it would when dragging to
the same filesystem.

How often does this happen? 
Always.

Additional Information:
This is either a documentation bug or a code bug
(the current behaviour is deliberate --
nautilus-dnd.c, line 359 onwards). I'd prefer it
if it had the behaviour described in the
documentation; when I drag a file, I'm almost
always moving it rather than wanting to copy it,
and the always-move behaviour doesn't require the
user to know what filesystem a folder is on to
predict what dragging a file will do.
