Not precisely true, as PWS mentioned.  This could perhaps be clarified
in the manual.  You can append ^y to a pattern but x^y doesn't imply
negation of the entirety of x, rather it means "x followed by anything
not y".  The precedence is also a little confusing; e.g., * has higher
precedence than ^ so

% print configure*
configure configure.ac configure.ac.orig
% print configure*^.orig
configure configure.ac configure.ac.orig
% print configure^*.orig
configure configure.ac

That is, in x^y the x pattern is fully expanded and then must not be
followed by the y pattern.
