Changing my vote:

p[q]                 -1
p + q               -1
p / q               +0
p.pathjoin()   +1

A method is essential, regardless of the color the bikeshed ends up.  As
far as operators go, / is the only option here that doesn't conflict with
string/collection APIs.  The alternative has an adverse impact on
subclassing and on future design choices on the path API.  This goes for
the method name too.
