	Significant cleanup to DO REPEAT.
	
	* repeat.c: (struct line_list) Rename struct repeat_line.  Use
	struct ll instead of explicit "next" pointer.  Make "file_name"
	const.  Change "const char *line" to "struct substring text".  Add
	`syntax' member.  Update all references.
	(enum repeat_entry_type) Rename repeat_macro_type, update all
	references.
	(struct repeat_entry) Rename struct repeat_macro.  Use struct ll
	instead of explicit "next" pointer.  Change "char[] id" to "struct
	substring name".  Change "char **replacement" to "struct substring
	*replacements".  Update all references.
	(struct repeat_block) Use struct ll_list for lists of lines,
	macros.  Change "cur_line" to struct ll *.
	(cmd_do_repeat) Don't bother adding an empty getl source at all.
	This saves special-casing an empty source in repeat_read.
	(parse_specification) Use new find_macro function.
	(find_macro) New function.
	(skip_indentor) Removed.
	(recognize_keyword) Change interface, update callers.
	(recognize_do_repeat) Ditto.
	(recognize_end_repeat) Ditto.
	(parse_lines) Use lex_preprocess_line to preprocess the input line
	to check for DO REPEAT and END REPEAT, instead of coding it
	inline.
	(parse_ids) Need to make a copy of the array parsed by
	parse_mixed_vars_pool, instead of using it verbatim, because we're
	using struct substring now.
	(add_replacement) Use struct substring in interface, instead of
	const char *, and update all callers.
	(find_substitution) Rewrite using substring, in terms of
	find_macro.
	(do_repeat_filter) Use struct substring to simplify code.
	(current_line) New function.

	Fix lack of ->name and ->location in DO REPEAT's getl_interface.
	See bug #15702.

	* repeat.c: (cmd_do_repeat) Initialize name, location in
	getl_interface.
	(do_repeat_read) Adjust semantics of cur_line so that, after the
	call, it points to the line just returned, instead of to the next
	line to be returned.  Thus, do_repeat_name and do_repeat_location
	can use cur_line to obtain the info they need.
	(do_repeat_name) New function.
	(do_repeat_location) New function.

	* repeat.c (do_repeat_read): Properly handle empty DO REPEAT...END
	REPEAT block.  Fixes bug #18407.  Thanks to John Darrington for
	reporting this bug.

	* repeat.c: Eliminated references to extern variable getl_buf.

	Fix memory leaks.
	
	* repeat.c: (parse_ids) Take pool parameter and allocate all
	memory from pool.  Reduce implementation from loop to single call
	to parse_mixed_vars_pool().
	(store_numeric) Removed.
	(add_replacement) New function.
	(parse_numbers) Take pool parameter and allocate all memory from
	pool.  Require ranges to be in increasing order.
	(parse_strings) Take pool parameter and allocate all memory from
	pool.

	Continue reforming procedure execution.  In this phase, get rid of
	many global variables, consolidating procedure execution in
	procedure.c.  Encapsulate transformations in new "struct
	trns_chain".  Also, change implementation of N OF CASES, FILTER,
	and PROCESS IF from special cases to transformations.
	 
	* do-if.c: (cmd_do_if) Use finalizer to ensure control stack gets
	cleared.
	(do_if_finalize_func) New function.

	* loop.c: (create_loop_trns) Use finalizer to ensure control stack gets
	cleared.
	(loop_trns_finalize) New function.

	* temporary.c: (global var temporary) Removed.  Changed references
	to use proc_make_temporary_transformations_permanent() or
	proc_in_temporary_transformations().
	(global var temp_dict) Removed.
	(global var temp_trns) Removed.
	(cmd_temporary) Reimplement in terms of
	proc_in_temporary_transformations() and
	proc_start_temporary_transformations().
	(cancel_temporary) Moved to procedure.c, renamed
	proc_cancel_temporary_transformations().
