[Python-3000] exclusion feature for 2to3?

[Georg Brandl]

In order to have a codebase run in 2.x and 3.x, via automated translated by
2to3, there should be some "exclusion feature" for single lines that tells
the refactorer not to touch those lines.

For example, if you have some object that still has an iteritems() method and
keeps it, it'll have to stay the same during translation.
Same goes, e.g., for methods named next(), has_key() etc.

Most obvious would be a special comment, something like

for x in curiousobject.iteritems():  # 2to3:keep
     foo(x)

Does that make sense?

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
