We should be doing something like: http://stackoverflow.com/questions/2536545/how-to-write-unix-end-of-line-characters-in-windows-using-python
versionbump.py no longer exists after bug 949600.
I don't think we should get this bug closed. Instead get it ported via bug 974184 for hg.m.o.
Agreed, but this will happen in bug 974184 now; duping there.
Actually not this one; we won';t be writing diffs any more.
