At the moment I don't think there is a good way in Tcl to get hold of
the stderr output if a subcommand returns a non-zero exit status, but
ignore it if the exit status is 0, other than by redirecting stderr to
a temporary file, which has its own problems.  Tcl can bundle stderr
in with stdout, or ignore it, or take it as an error indication, or
send it to a file.

So if git commands can avoid writing non-error messages to stderr,
that will make my life easier...

In that case, Junio, perhaps we should restrict this particular warning
just to merge.

However, there a number of other warnings that can get printed on
stderr, many of them related to reflogs. So I suspect with some reflog
conditions (like a reflog that only goes back 1 day) you could end up
with a tcl error for "gitk HEAD@{2.days.ago}".
