| Read the regression test.  In particular:

Yes, I know and the reason I am asking is that I recall that another
section -probably from an earlier revision- used to say that any
number of trailing slashes can be ignored in any pathname, that is
why we see today's lossage on solaris and other svr4 variants where
the above two examples work. Since this involves changes to namei(9)
I just want to make sure we are not going to go the same way if we
don't have to.
