Yep. This has been broken for some time, too. I bisected it down to
cad3a205 from last year, which is in v1.5.3.
It's yet another incarnation of the same bug we keep seeing (which I
suppose is why you cc'd me). Anytime you look at the config before
running setup_git_directory, it screws up the GIT_DIR calculation for
bare repositories. AFAIK it's a bad interaction between the lazy setup
in setup_git_env and the magic in setup_git_directory.
I'm sure there is a "right" solution but I haven't had time to figure it
out yet. In this case, we are looking at the config to get the value of
core.pager. As a workaround, you could try doing that lookup in the
forked pager child (however, I don't think that would work on platforms
where run_command doesn't use fork).
