lsx-comp --trace option that inserts (top-level rule) line numbers in output

[unhammer]

We could compile a (larger) fst that outputs line numbers in the stream for every top-level rule application.

nob-nno has a PoC using xsltproc:
apertium/apertium-nno-nob@6d2a7e0
but would be nicer to have an lsx-comp --trace (also, nob-nno uses awk for line numbers, it will break if someone writes <e in the wrong place)

See if lsx-comp --debug does what you want.

lsx-comp -d lr apertium-nno-nob.nob-nno.lsx foo.bin (direction still required)

Doh, sorry. I blame lack of sleep.

But that's pretty great :-) It would be nice if it also inserted an end-marker, but in the meanwhile I can just use a simplified xslt
