`git diff` seems to implement its own paging system, or somehow
include less automatically when doing a diff and allows for a
colourful diff while with paging. Sometimes this feature is annoying
but most of the time it is very nice. What are the changes a switch be
added to `hg diff` or an extension to do that?
