Log message:
	add indentation to tracing
	The result is quite nice.
	The code is a little gnarly how to decides to insert newlines but
	the result is good.
	Because sometimes outdent is because the operation is marked as such,
	e.g. call_direct or end_procedure and sometimes it is by
	getting the tail operations like params or fields
	(notice that params are counted, locals are not, and some locals
	follow params, e.g. "_result" so the formating is a bit off)
	probably the multiplier shouldn't be sprinkled around either
	and the space string construction could be more general and efficient,
	i.e. grow it as needed instead of hardcoded size
	
	e.g.
	
	(118) declare_procedure  quoted_string:Text__Length ...
	(119)     declare_local  quoted_string:i  ...
	(120)     declare_param  quoted_string:t  ...
	
	(121) declare_local  quoted_string:_result ...
	
	(122) declare_procedure  quoted_string:Text__Empty  ...
	
	when what you want is:
	
	(118) declare_procedure  quoted_string:Text__Length  ...
	(119)     declare_local  quoted_string:i  ...
	(120)     declare_param  quoted_string:t  ...
	(121)     declare_local  quoted_string:_result  ...
	
	(122) declare_procedure  quoted_string:Text__Empty  ...
	...
	
	Rewrite fmt_uid, for brevity and to avoid signed math.
	(table lookup instead of if ladder)
	(bikeshed perhaps)
	
	a little cleanup/cosmetic:
	memcpy instead of strcpy a constant (zzz)
	remove comparisons to zero in boolean context
	remove some braces
	remove spaces at ends of lines (thought I already had)
	
	forgot to mention earlier:
	start, barely, consolidating the trace options
