Yes, looked it up in the Pickaxe, and indeed that's what it says.

This is from man perlre: 
       m   Treat string as multiple lines.  That is, change "^" and "$"
    from matching the start or end of the string to matching then
    start or end of any line anywhere within the string.

This should go on the page I've seen somewhere with gotchas.
Perl RE is quite widespread, and when ruby deviates from it it's
easy to trip up.
