What if the user didn't set the flag?  The first time I got an EPERM
trying to modify a chflagged file, it took be a while to figure out
what was going on, and I already *knew* about flags.  A random user
isn't going to know.  I'm not sure how to solve this problem - rm
isn't the only program that could trip over this - but it definitely
is a problem, and blaming the user isn't going to solve it.

I'm not sure it can be solved without breaking POSIX compatibility -
can ls be modified to print flags that could cause an EPERM if they
are nonzero and the -l flag is given?
