Apologies for the 2 late-night bugs

Hi,

with the recent patches to introduce $HOME/.gitconfig, I also introduced 
two bugs. They were not due to lacking of testing, but rather due to 
testing with an accidentally set GIT_CONFIG. And now I *know* why I did 
not want that thing in the first place. And I decided not to become a 
pilot, ever.

Ciao,
Dscho
