[Numpy-discussion] please close 611, 629, 2490, 2264

[Eric Firing]

Github issues 611, 629, and 2490 are duplicates.  611 included patches 
with a test and a fix, both of which were committed long ago, so all 
three issues should be closed.

Please see my comment on 2264 as to why that should be closed.

On 1417, please remove the "component:numpy.ma" label and add the 
"component:matrixlib" label.
