Delete "for the time being".

That part of the language reference manual is no longer correct;
it's been made obsolete by the following NEWS item:

 | * The Mercury compiler can now handle arbitrary mappings from source files
 |   to module names.  If the program contains modules for which the source
 |   file name does not match the module name, before generating the
 |   dependencies the command `mmc -f SOURCES' must be run, where `SOURCES'
 |   is a list of the names of all of the source files.  If the names of the
 |   source files all match the contained module names, `mmc -f' need not be
 |   run.
                                                                                
This problem is not a result of your change, though.
