[Bf-animsys] About rotation limits beyond +/- 180 degree

I found a question on blender.stackexchange about bone rotation limits.


I was curious and looked into that. And i found that indeed setting the 
limits > 180 does not work from a user point of view.


Here the pink range can not be reached  although it is in the defined 
limits range. Instead of that the bone flips back to 0 when user tries 
to rotate beyond 180 although the limit range would allow that.

The wiki documentation does not mention this behavior:


Now my question is:

- is it a bug ? (then imho it should be fixed)
- or is it a limitation ? (then it should be documented)

Actually from a user point of view setting the limits to values > 180 
could make a lot of sense. The behavior of the constraint then seems 
somewhat "unexpected". So if this is a limitation that can not be 
avoided, then what about limiting the input values for the limit ranges 
to -/+ 180 ?

What do you think ?
