Yes. But my question was more subtle. I know it can be done with the
's' command in sam now. But I asked sth. different. The documentation
(paper about sam) says 's' is redundant. But it seems (only seems
since documentation says nothing), that submatches only work with the
's' command. If this is true 's' is not redundant, since if it weren't
there you would not have any chance to use \1, \2, etc.
That was the reason I wanted to have my example rewritten WITHOUT the
's' command...

But anyway thanks!
