The pagination functionality in git am has some problems:
- It does not check if stdout is a tty, so it always paginates.
- If $GIT_PAGER uses any environment variables, they are being
ignored, since it does not run $GIT_PAGER through eval.
- If $GIT_PAGER is set to the empty string, instead of passing
output through to stdout, it tries to run $dotest/patch.
Fix them. While at it, move the definition of git_pager() to
git-sh-setup so authors of other commands are not tempted to
reimplement it with the same mistakes.
