There is a difference because the perl parser was always incorrect (at
least since \s includes non ascii spaces).  In the XS parser whitespace
characters are listed explicitely, in the perl parser it is up to the
definition of perl, so it is in general different without /a nowadays (if
I understand well).  So, the perl parser is incorrect since some time,
but there was no example in which there was a difference since it is the
first example with non ascii space.  But non ascii spaces here and there
would show the difference between the perl parser and the XS parser.

Anyway I will shortly commit a fix.
