It will still do _some_ object lookups. In particular, it will do the HEAD 
lookup in 'print_ref_list()', even if it's not strictly necessary. But it 
should cut down the noise further.

And this (on top of them all) will basically avoid even that one.

Ok, I applied (both) on top of the first one.

After 7 tests I got these, 

time:

      0.61 +/- 0.08

GIT_DEBUG_LOOKUP=1 git branch |wc -l
    
      9
      
which are in fact only the branches list.

Compared to yesterday, that is a huge improvement (0.6s vs 5.7s)
and (9 vs 2200+). At least for me 0.6s is "instantaneous", so
the issue is really gone.

Thanks a lot to everyone!
