Unrelated cleanup.
I can extract these to a separate changelist if you prefer.

[abarth-chromium, 2013/07/03 03:47:37]

I don't think this works.  ASCIILiteral needs to be applied to the actual
literal so that it can autodetect the length.

[abarth-chromium, 2013/07/03 04:07:00]

Oh, actually, you're right.  ASCIILiteral doesn't autodetect the length.  It
just saves the copy.
