Is there a point in doing this loop if we are not going to eval
after all? IOW...

... I am wondering why it is not more like this
if options=" $incl $(__git ${cmd/_/ } --git-completion-helper) "
then
for i in $excl
do
options=...
done
eval "$var=..."
fi
or just return from the function instead of introducing and setting
a new variable, as only remaining thing the function does is to call
__gitcomp with $options, but we know that we are giving up on
completing this round.
