Added the possibility to propagate translators onto directories. Fixed bugs.

Now the user can enter directories using the following command:
  cd dir,,x
All files in this directory will then be implicitly translated
by translator 'x'; in other words, if there is a file 'file' in
directory 'dir', after executing the command mentioned above,
and after running
  cat file
the user will obtain the content of 'file' translated by 'x'.

Also fixed several rather serious bugs in lookup of file names
of the type 'file,,x'.
