Bug in loop-report when using blank space

[Rombur]

There seems to be a bug in loop-report if there is a blank space in the name of the loop. In that case, the Loop summary works fine but the Iteration summary does not print anything. The cxx-example uses mainloop and everything works fine:

./cxx-example -P loop-report 5000

Loop summary:
------------

Loop     Iterations Time (s) Iter/s (min) Iter/s (max) Iter/s (avg)
mainloop       5000 7.020397   371.149326  2408.294927   690.052330

Iteration summary (mainloop):
-----------------

If I just change mainloop to main loop and here is what I get:

./cxx-example -P loop-report 5000

Loop summary:
------------

Loop      Iterations Time (s) Iter/s (min) Iter/s (max) Iter/s (avg)
main loop       5000 7.041216   373.641304  2430.606873   689.089144
