Thanks, but ~ changes from xx01m to xx01mkf (which is correct) between
a few commands in .bashrc:

If I add:

. ~/.git-completion.bash
if [ ! $? = 0 ] ; then
  echo "HOME=" $HOME
  echo "~=" ~
  echo "~/.git-completion.bash=" ~/.git-completion.bash
fi

I see (*sometimes*):

-bash: /home/xx00m/.git-completion.bash: No such file or directory <<<wrong
HOME= /home/xx00mkf
~= /home/xx00mkf <<<correct
~/.git-completion.bash= /home/xx00mkf/.git-completion.bash <<<correct
