I think it's a bug. It bisects to Jonathan's dec543e (am -i, git-svn:
use "git var GIT_PAGER", 2009-10-30). But it seems to me that "git var
GIT_PAGER" is fundamentally broken. It calls git_pager, which in turns
checks isatty(1). But of course stdout _isn't_ a tty, because we are
piping it back to the perl process to read the result of "git var".
In other words, I don't see how this ever could have worked.

For git-config's colorbool support we have the caller pass in a
stdout-is-tty flag. I suspect we would need to do the same thing here.
