Yes, you are right, I started with a different need and then it changed

I reply here to all of you about such point: that's not important, 
although I appreciate very much your suggestions!

In respect to this, I thank Peter for his analysis.
Probably Perl has a different pattern matching algorithm.

Thanks again to all of you!
