SPUG: Word boundry regex treated differently by 5.6 and 5.005033

Hey all,

I noticed something that seems strange.  I ran the following
script on two machines.  One of them running 5.00503 and one
running 5.6 (full details attached) and got two different


use strict;

my $text = "Charles Bronson";

$text =~ s/\B\w//g;

print "here it is: $text\n\n";

output on 5.6 was:	here it is: Cals Bosn
output on 5.00503 was:	here it is: C B

I appears as though 5.00503 is getting rid of all \w
characters in the string that aren't preceded by a word
boundary(which is what I expected), while 5.6 is removing
every other \w character in each word.
I couldn't see anything obvious in perldelta that would
indicate that the two versions should treat this
differently.  Does anyone know why this might happen?

P.S. Joydesk doesn't lend itself well to pasting wide lines
of text so i've attatched the full details of my perl
