As Colin mentions, it has always been like this: 'hg diff' operates on
the repository version of files. So you will get output with LF (Unix
format) line endings in your terminal. I asked Patrick on IRC and he
confirmed this and explained that it's no problem for the Windows
terminal to handle LF output (i.e., it wraps the lines correctly).

The reason why we want to produce the same output on all platforms is to
ensure that 'hg diff > patch' gives you a correct patch on all
platforms. In other words, the patch should use the line endings of the
files in the repository instead of the line endings in your working
copy. That ensures that everybody can apply the patch without using
special extensions (they can even use patch(1) to do it).
