Re: [PATCH 4/6] 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.
