Re: Cheetah completely borked under python 2.7?

  The remaining failures (6 of them) are line endings tests. Python 2.7
changed the behaviour of the compile() builtin (change documented
at http://docs.python.org/dev/whatsnew/2.7.html). The following
minimally reproduces the change:

c = compile('x="""\r\nx\r\n"""', 'file', 'exec')
exec(c, globals(), locals())

print x == "\nx\n"

Under 2.7 this prints "True". Under earlier versions of python, it prints
"False".

I can't see a way round this short of replacing all in-string literal 
newlines
with "\r\n" or "\r". This would require pre-parsing the template to find
the strings. Hopefully there's a nicer way.

We don't actually care that literal line endings get converted to UNIX
line endings; does this matter to anyone? Would it be easier to require
non-UNIX line endings to be escaped?

Thanks

Jon
