There is also a related set of fixes for spawning externals via fork,
which fixes a bug with the pager not getting cleaned up. But it looks
like it is also in the version you tested.

Can you give a more complete recipe for reproducing? Since I was just
touching this area in git, I want to make sure it isn't a git bug you
are triggering. :)

As an aside, I found some related weirdness. In my git repo, if I do
this:

  $ git checkout next
  $ eg log -p

I get log output, but the diff is not colorized (and I have color.diff
set to "auto" in my ~/.gitconfig). But if I detach my HEAD and show the
log:

  $ git checkout next^0
  $ eg log -p

then I _do_ get color in the patch. I also get this error:

  Use of uninitialized value $branch in concatenation (.) or string at
  /home/peff/eg line 2854.
  eg: command (git rev-parse refs/heads/) failed
  eg: received signal 13

The error is easy to explain. The offending code is:

    my $branch = RepoUtil::current_branch();
    my ($ret, $revision) =
      ExecUtil::execute_captured("git rev-parse refs/heads/$branch");

So it is clear that you just need to handle the case of there being no
current branch. But the color thing is certainly exotic. :)
