New submission from Paul Bonser:
lib2to3.pgen2.tokenize:detect_encoding looks for the regex
"coding[:=]\s*([-\w.]+)" in the first two lines of the file without first
checking if they are comment lines.
You can get 2to3 to fail with "SyntaxError: unknown encoding: 0" with a single
line file:
coding=0
A simple fix would be to check that the line is a comment before trying to look
up the encoding from that line.
