Comment 5 for bug 1780775

The second patch here attached alters the tip information displayed
during path node editing, to more accurately describe the actions
available for the control that the mouse is currently hovering over, as
discussed above.

Unlike the first patch, it does not alter Inkscape's actual
functionality in any way. I have separated the two, because the
information text will presumably require internationalization.
Hopefully, the first patch can be applied immediately (it seems to work
perfectly), and the second when translations of the new and altered text
are available.
