is_mangled

[Christopher R. Hertel]

Perhaps I'm splitting hairs but Jeremy warned me about playing around
inside mangle.c.  I've written a new is_mangled function which is a bit
more selective and doesn't use recursion.  The main behavioral change is
that it tests the two characters following the magic character to see if 
they are in the basechars set.

If no one objects, I *will* make this change.

int is_mangled( char *s )
  {
  char *magic = strchr( s, magic_char );

  if( !magic || (strlen(magic) < 3) )
    return( 0 );

  if( strchr( basechars, toupper(magic[1]) )
   && strchr( basechars, toupper(magic[2]) )
   && strchr( ".", magic[3] )
    )
    return( 1 );

  return( 0 ); 
  } /* new_is_mangled */
