 0.4:
	o Applied patch by Andreas Feldner <pelzi@flying-snail.de>
	  which fixes the following things:
	    - the destructor tried to free the sub_vec vector,
	      even if *this has not been used and thus it is uninitialized.
	    - the destructor does now only free such objects that
	      are initialized
	    - the copy constructor takes now a const Pcre& instead of
	      just a Pcre& because this object is read-only
	    - the operator= was weird, in fact it did not really work
	      as one should expect. it created a new Pcre oject instead
	      of initializing *this with the given expression and returning
	      *this, which it does now.
	  Thanks to Adreas.
	o Added an empty constructor for convenience
	o Added operator= (const Pcre&) suggested by Andreas, which allows
	  one to copy one Pcre object into another
	o Added private method zero() which initializes all pointers with
	  NULL. zero() is called from every constructor and operator=
	o Added function mycopy() to sample.cc to demonstrate the use
	  of the new constructors and operator= stuff.
