Not really. __git_ps1 and __gitk seems to do __gitdir very early to make
sure anybody that use $__git_dir can rely on it, but having to sprinkle
"set up $__git_dir variable" everywhere means anybody who wants to update
need to know if it is already called, which defeats the point of "we can
use $__git_dir instead of calling $(__gitdir)" from maintainability's
point of view.
