Oh, but it looks really weird to me. "-f" is meant to accept one
argument, but we're giving it the result of wildcard expansion, no?
And why do we use "ls" where I think "echo" would be sufficient?
I'd appreciate a more obviously correct implementation, where we would
know why exactly it works. ;-)

Thanks for explaining this. At this point, I am not sure which one is a
better choice for -jumbo-4. One explicitly requires gmake, the other is
weird and it might break elsewhere, maybe even with gmake.
As to the sed's, can one of you actually test them on Solaris, please?
