Ahh, you are right; there is no '|'-alternation in BRE.

We of course could do something like:

    good=" .*/objects/$x2/${x38}_$x40 HTTP/[.0-9]*" 20[0-9]\""
    grep -e "\"PUT $good" -e "\"MOVE $good"

But that's too ugly.

I don't mind Perl as we already depend on it; the looseness of the regexp
stil bothers me somewhat, though...
