Hmm, why? It's an atomic change, one part doesn't make sense without the
other.

Aha, ouch - I understood that it is only an optimization. :-(

So AIUI, there are several possibilities:

  (i) Makefile will autodecide on whether git-gui will be
built+installed or not

  (ii) ./configure will, people not using configure and building on
servers will be left to tweak config manually

  (iii) ./configure will, git-gui will default to not to be built and
people not using configure and wanting git-gui will be left to tweak
config manually

I suspect that (ii) will be chosen, and even though I don't like it
*personally* I guess it's the most reasonable approach for the general
public. I didn't know that tclIndex is vital for git-gui when I
submitted the patch, the /Makefile comment suggests otherwise.
