Yikes, you’re right.  Sorry about that.

Thanks for the helpful reference.  I think it is simpler for the caller
to disable the pager himself, i.e., something like patches 2, 4, and 5
below:

Jonathan Nieder (6):
  Fix 'git var' usage synopsis
  Make 'git var GIT_PAGER' always print the configured pager
  git.1: Clarify the behavior of the --paginate option
  git svn: Fix launching of pager
  am: Fix launching of pager
  tests: Add tests for automatic use of pager
