[issue2631] IMPORT_NAME Documentation is incomplete

[Paul Bonser]

New submission from Paul Bonser <[EMAIL PROTECTED]>:

The documentation for IMPORT_NAME at
http://docs.python.org/lib/bytecodes.html doesn't mention the fact that
the instruction requires two parameters to be on the stack.

TOS and TOS1 should map to the fromlist and level parameters to the
builtin function __import__, respectively.

[issue18873] "Encoding" detected in non-comment lines

[Paul Bonser]

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.
