Subject: pager: do allow spawning pager recursively
MIME-Version: 1.0

This reverts commit 88e8f908f2b0c56f9ccf8134d8ff9f689af9cc84, which
tried to allow

    GIT_PAGER="git -p column --mode='dense color'" git -p branch

and still wanted to avoid "git -p column" to invoke itself.  However,
this falls into "don't do that -p then" category.

In particular, inside "git log", with results going through less, a
potentially interesting commit may be found and from there inside
"less", the user may want to execute "git show <commit>".  Before
the commit being reverted, this used to show the patch in less but
it no longer does.
