Bug#237323: Diff output should be piped to pager

[Mark J. Nelson <mjn@anadrome.org>]

(Triaging old bugs.)

Although I agree the default should probably use a pager, for what it's
worth, this can be set in the config file as well. The 'diff' variable
controls what command is used to diff. By default, it is,

diff = diff -u CURRENT2 CURRENT1

(CURRENT1 and CURRENT2 are magic strings replaced with the two
filenames.)

You could change this to,

diff = diff -u CURRENT2 CURRENT1 | pager
