.profile not being read from $HOME

It's a documentation problem.  "sh" is supposed to read .profile from the
current directory.  This doesn't cause a problem, because you aren't
supposed to run login shells (i.e., shells with argv[0] equal to "-sh")
unless you're in the user's home directory.

All other UNIX systems behave the same way.
