If you have been running "GIT_PAGER=cat git whatever" and the like,
we did not pipe the output through "cat" and this has been the case
for a long time. The only thing the patch in question changed is
for those who build with
make DEFAULT_PAGER=cat
and I doubt that you have been debugging git by rebuilding it with
such a setting, so....
