Did some lint script complain about """ without a blank line?

[jeffcarp, 2016/11/03 22:33:00]

No, it was has_changes_in_wpt that couldn't handle it. I changed it to be this
way due to your earlier comments about not needing to test first blank lines
explicitly (maybe I misunderstood). Either way, I'm about to change this to:

return ("foo\n"
        "bar\n")

Which seems cleaner and more pythonic

These and the following in the same style as the first, whatever it turns out to
be.

[foolip, 2016/11/03 23:40:31]

Wait, now missing newlines? (On phone, can't seem to click to write new issue.)

[jeffcarp, 2016/11/03 23:54:07]

Yes, sorry maybe I'm confused. I thought you said it was okay to remove the
newlines from the test and just assert in the code.

Copypasta, should have been like above but with .txt?

[jeffcarp, 2016/11/03 22:33:00]

Oops thanks for catching this!
