Test choice of pager at several stages of repository setup. Some
patches under consideration will produce different results for
different commands, so it should be useful to have examples like this
in mind to illustrate their effect.
Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

Changes from v1:
- Use /bin/sh instead of $SHELL_PATH to simplify quoting issues
- Split the test_pager_choice function into single-test pieces to
make the test easier to understand.
I’ll resend the patches 3 and 9 with corresponding adjustments in a
moment.
Thanks to Hannes for the feedback.
