Orthogonalization refuses to work on some almost-orthogonal shapes

[bilbo]

Seem the orthogonalization refuses to do anything and just spit error message when even one tiny segment of way have angle about 45 degrees in relation to rest of the segments.

In attachment there is example of such way.

This error message is thrown even when I explicitly select two nodes on the way to specify the orthogonalization direction.

While it may be useful for newbies so they won't accidentally orthogonalize something that should not be orthogonalized, I think the orthogonalization action should be a bit less picky about what to orthogonalize and not and it should never fail when I explicitly pick two points. (there is an undo function after all .... )

OK, no more nagging...
