yangguo@chromium.org aa3518a0f3 Make sure files end with exactly one new line and police this in presubmit. 
The changes are (excluding presubmit.py) mechanical. I added the following
lines after the check and iterated the presubmit script until all errors
went away:

f = open(name, "w");
if contents.endswith('\n\n'):
  f.write(contents[0:-1])
else:
  f.write(contents + '\n')
