Python3 removes os.getcwdu() and introduces os.getcwdb(). The patch is 
a fixer for lib2to3 replacing "os.getcwdu()" to "os.getcwd()", 
and "getcwdu()" to "getcwd()". I hope that nobody defined its 
own "getcwdu()" function :-)

cwd = os.getcwdu()
print "cwd=%s" % cwd

from os import getcwdu
cwd = getcwdu()
print "cwd=%s" % cwd

 import os
-cwd = os.getcwdu()
-print "cwd=%s" % cwd
+cwd = os.getcwd()
+print("cwd=%s" % cwd)

-from os import getcwdu
-cwd = getcwdu()
-print "cwd=%s" % cwd
+from os import getcwd
+cwd = getcwd()
+print("cwd=%s" % cwd)

(there is currently no patch attached)

I don't think getcwd() should be fixed as getcwdb(). It's not possible
to tell what the intention of the call was, in which case I recommend
not to change the code at all.

I concur with Martin; getcwd should not be converted to getcwdb.

You're patch looks pretty good. Could you write tests for it, though?
Also, I don't think you need to handle the second case of a bare getcwdu.

My patch doesn't work, that's why I don't write unit test :-)
 - os.getcwdu() was correctly replaced
 - getcwdu() was also replaced
 - but not "from os import getcwdu"

Since most people use os.getcwdu(), and that 2to3 is unable to make sure that 
getcwdu() comes from os or is an user defined module, I prefer to only keep 
the first fixer (os.getcwdu() => os.getcwd()). The new patch include a test.

(Let's try Roundup by email using an attachment :-))
