$xdiffentry is set to something like {{pph asm diff 123456}}, so i
need tr and cut to extract 123456

(i tried removing the tr and i get "123456}")

and the sum of $diff_result is something like "123456     12", i'm
ignoring the second number for simplicity; hence why i'm using cut
here.

If there are ways to do this directly in TCL, without using exec
calls, I'd be glad to know.
