[josm-dev] Request to apply a small patch about the alignment in circle and rotate objects functions

[Pieren]

Dear Josm-dev,

Could someone commit the following two changes regarding the features "align
nodes in circle" and "rotate objects" ?

As I said in a previous email, a node initialized with LatLon(0,0) may have
completely wrong EastNorth values (at least for the Lambert projection).

Here is the change in AlignInCircleAction.java (thank you Matthew):

And here is the change in RotateCommand.java (same cause with the same side
effect) :
