If the slashdot function is to cope with parent directories it needs also
to convert ^ to .. . Thus:

 slashdot = \(s)
   local slash,dot,dot2,up,pat = '/','.','..','^','[%.%^/]'
   local change = {[slash] = dot,[dot] = slash,[up] = dot2}
   =>(s:gsub(pat,change)) end

I suppose it ought also to change & to . but I have never seen anybody
describe a relative path "foo" as "&.foo". So maybe it is best to let
sleeping ampersands lie.
