	* html.c: (change_attributes) Dead code, removed.
	(escape_string) Eliminate code to call change_attributes() that
	never actually called it.
	(output_tab_table) Get rid of dependence on tab_hit
	and struct tab_joined_cell's hit member, which are abominations.

	* tab.c: (tab_output_text) Don't call
	d->class->text_set_font_by_name if it's a null pointer.
	(macro UNROLL_LOOP) Eliminate.
	(macro UNROLL_3_LOOPS) Eliminate
	(tabi_render) Rewrite not to use the above macros.

	Start working on a new output driver system, one that doesn't suck
	so much, by adding a "device-independent" output driver.  The idea
	is to write out only a single output stream, then use separate
	processes to translate them into whatever formats we want.  This
	is similar to how "groff" works with its various output drivers
	(grops, grotty, grodvi, ...).

	* Makefile.am: (pspp_SOURCES) Add devind.c, devind.h.

	* list.q: (write_all_headers) Stub out devind class.
	(clean_up) Ditto.
	(determine_layout) Ditto.
	(list_cases) Ditto.

	* output.c: (outp_init) Add devind class.

	* devind.c: New file.

	* devind.h: New file.

	* frequencies.q: (hash_value_alpha) Fixed up the previous change
	to use the proper string length.
