Yeah, showbranch.default really seems pointless now. Especially
confusing is the fact that it doesn't do whitespace-splitting, so you
can't do:

  git config showbranch.default "--topo-order branch1 branch2"

but instead have to set multiple config variables.

I think deprecation makes sense, but I am in no hurry to get rid of it.
I mainly just wouldn't want people to think it was a useful thing to
learn. :)

I think it could actually just be switched to use ALLOC_GROW.
