D803: extdiff: use pager

[indygreg (Gregory Szorc)]

indygreg added a comment.


  Before I accept this, I think we should have a brief conversation on the possibility that an external diff tool invokes its own pager.
  
  Do we need a per-diff tool config option to control whether hg invokes a pager? I think hg using a pager by default makes sense. But I also suspect there will be an external diff tool that doesn't like this behavior.
