So I will commit it and post it as a diff (for completeness).

I have another question on you concerning lex.

Some years ago I adapted a copy of lex so that the context returned would be not 
just byte offset but also the line number:

:- type context
     ==      {offset, lineno}.

and also changed the output type for

:- pred read(io__read_result(Tok),
             lexer_state(Tok, Src), lexer_state(Tok, Src)).
:- mode read(out, di, uo) is det.

to

:- pred read(lexer_read_result(Tok), lexer_state(Tok, Src),
             lexer_state(Tok, Src)).
:- mode read(out, di, uo) is det.


where

:- type lexer_read_result(Token)
     --->    ok(Token, context)
     ;       error(string, context)
     ;       eof.

My version is now out of sync with yours. Would you mind if I made the same 
changes to your version?

Thanks, Ondrej.
