True, I should have stressed that.  Thanks.  Also in the same
sense (but to a lessor degree), "test" vs "[" is also
portability issue.

What about:

	parents="$parents $(git-rev-list --max-count=1 --parents $c | cut -b42-)"

I just used that trick recently.  Oh yea it was in git-gui's
GIT-VERSION-GEN script.  Though I did not know about using cut
like that...

I used to stay away from 'cut' myself, although it is not too
bad for portability these days.  I would probably have done the
above with a single sed process, though.
