[RFC] Cleanup for make_source_files_completion_list

[Keith Seitz <keiths@redhat.com>]

Hi,

make_source_files_completion_list is only ever called with the first 
parameter twice, e.g.,

   fn_list = make_source_files_completion_list (text, text);

Is there any reason to not whack the second parameter as the following 
patch does?

	* symtab.h (make_source_files_completion_list): Remove unused
	second parameter.
	* completer.c (location_completer): Update call to
	make_source_files_completion_list.
	* symtab.c (maybe_add_partial_symtab_filename): Likewise.
	(make_source_files_completion_list): Remove unused second
	parameter.
	Pass text to add_filename_to_list instead of word.
	Set datum.word to text, too.
