Bug processing example in docs

[joel-dodge]

I am seeing some funny behavior in rendering examples in docs. If I comment out all but the first two lines I see the doc nodes that I expect (which are the ones that already existed prior to this change). If I add in a third line, The example renders as having one more empty input regardless of what the line was - and no output. If I add in a fourth line the example rendering breaks.

This example works locally for me as in :

i1 :     F = QQ^4
          wp = wedgeProduct(1, 1, F)
          L = exteriorPower(1, F)
          R = exteriorPower(1, F)
          wp * (L_0 ** R_0)
          wp * (L_0 ** R_1)

o1 = QQ

o1 : QQ-module, free

o2 = | 0 1 0 0 -1 0 0 0 0  0  0 0 0  0  0  0 |
     | 0 0 1 0 0  0 0 0 -1 0  0 0 0  0  0  0 |
     | 0 0 0 0 0  0 1 0 0  -1 0 0 0  0  0  0 |
     | 0 0 0 1 0  0 0 0 0  0  0 0 -1 0  0  0 |
     | 0 0 0 0 0  0 0 1 0  0  0 0 0  -1 0  0 |
     | 0 0 0 0 0  0 0 0 0  0  0 1 0  0  -1 0 |
