Summary: bz2.BZ2File doesn't handle modes correctly

Initial Comment:
I've noticed that if I specify a file mode of 'U' to bz2.BZ2File, it will 
erase my file.  That's bad.  Specifying 'rU' works as expected.  
Basically, it assumes that you want a writable file unless it sees an 
'r' in the mode, or no mode is given.  Ugh.

I've attached a patch that fixes this on CVS HEAD, it looks like it 
should apply cleanly to 2.4 as well.  This is a backport candidate if 
I've ever seen one.
