Some filesystem nits

[Matthew Dillon]

:Our error message is dumb to say the least. :P
:And question is whether we want to allow a user to remove a directory which
:is in the path of the cwd.

:-- 
:Jeroen Ruigrok van der Werven <asmodai(at)wxs.nl> / asmodai / kita no mono

     Well, we definitely do want to allow removal of a directory in the
     path of the cwd, that's the BSD way :-)

     The error message is bogus.  I thought I had fixed that but apparently
     not.  I'll try to get to it today sometime.
