These work:

http://<server>/<tracker>/issue?:filter=status,assignedto&status=1&status=2
http://<server>/<tracker>/issue?:filter=status,assignedto&status=-1,1,2,3,4,5,6,7

This doesn't:
http://<server>/<tracker>/issue?:filter=status,assignedto&status=-1,1,2,3,4,5,6,7&status=1

It fails in the bowels of back_anydbm.filter (traceback
below), and I
couldn't easily see what the current algorithm is or
whether there's
one that would cope with the above situation. And I
don't know what
the impact for the other backends would be.

Is this kind of search something that Roundup wants to
deal with at
all? It could certainly be useful:

  <input value="5,6" type="checkbox" name="locality">Local
  <input value="1" type="checkbox" name="locality">Down
Under
  <input value="2" type="checkbox" name="locality">Up Above
  ...
  <input value="5" type="checkbox" name="locality">In
the Middle
  <input value="6" type="checkbox"
name="locality">Western Cape

So I could check "Local" and "Down Under",
instead of "Down Under", "In the Middle", and "Western
Cape".
Currently it's either predefined searches ("5,6"), or
individual
choices, but not both together.
