User Friendly is not Computer Friendly - paths in error tracebacks

[Gavin Kistner <gavin@...>]

I have a (Ruby) script that runs a Lua script, catches output to  
stdout and stderr, and makes some HTML output which, among other  
things, provides links to the file/line where an error occurred.  
(This is for TextMate on MacOS X.)

Unfortunately, when the path is long, the lua standalone runtime  
'helpfully' truncates the paths:

lua: ./../orxit.lua:6: wtf
stack traceback:
	[C]: in function 'assert'
	./../orxit.lua:6: in function 'jibble'
	...s/gavinkistner/Desktop/pork \ % : butt/bling/tmp.lua:12: in  
function 'explode'
	...s/gavinkistner/Desktop/pork \ % : butt/bling/tmp.lua:7: in  
function 'bork'
	...s/gavinkistner/Desktop/pork \ % : butt/bling/tmp.lua:15: in main  
chunk
	[C]: ?

Ignoring the pathological directory name I have there, I have the  
problem that the interpretter chopped off the leading "/Users/".

Is there any way to tell the runtime NOT to do this truncation? If  
not, would someone more familiar with the internals than I be kind  
enough to provide a patch for 5.1 that leaves the full paths intact?

TIA,
Gavin
