Bit confused about what this shell fragment does. It doesn't look as
if it would be safe given command line arguments containing spaces
either.
How about using getopt?

I did it with getopt first, it did not take -h into account
unless it was
the first argument and giving confusing answer.
Offending string could be "this is -h the one". Is it (preferably
easily) solvable?
