I do not use show-branch myself, but being consistent with the other
porcelain commands makes sense to me.

I don't think the problems described in daa0c3d97 should be an issue for
us, as the purpose of that commit was to delay the color decision until
the last minute. That helps commands which load color config before
having decided on whether to use a pager. In other words, it covers the
exact situation you introduce here:

So I think your patch is fine with respect to those problems.

However, I do not see any need for show_branch to delay its pager setup
at all. Commands like "git diff" and "git log" must do so, because they
do not know whether they want a pager or not until after parsing
command-line arguments. But in this case we are always starting the

Would it make more sense to just set the USE_PAGER flag in the
"show-branch" entry in git.c (see the "shortlog" entry for an example)?
