File gm/tests/run.sh (right):

https://codereview.chromium.org/128793002/diff/1/gm/tests/run.sh#newcode10
gm/tests/run.sh:10: # TODO: because this is written as a shell script (instead
of, say, Python)
The long-term fix is to re-write the GM self-test:
- in Python : https://code.google.com/p/skia/issues/detail?id=677
- so it is less fragile : https://code.google.com/p/skia/issues/detail?id=1068

But for now, I want to turn this step from red to green with the tiny fix below.
