git svn: Fix launching of pager

In commit dec543e (am -i, git-svn: use "git var GIT_PAGER"), I tried
to teach git svn to defer to git var on what pager to use. In the
process, I introduced two bugs:

- The value set for $pager in config_pager has local scope, so
run_pager never sees it;

- git var cannot tell whether git svn’s output is going to a
terminal, so the value chosen for $pager does not reflect that
information.

Fix them.
