From f6dff119d51e0067d213068093039bb2f939d139 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Sun, 14 Feb 2010 23:04:13 -0600 Subject: [PATCH] am: Fix launching of pager 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.
