Just one remark: my lpeg is

/*
** $Id: lpeg.c,v 1.98 2008/10/11 20:20:43 roberto Exp $

and doesn't have the lpeg.Ca pattern. The lpeg that comes with luatex is

/*
** $Id: lpeg.c,v 1.86 2008/03/07 17:20:19 roberto Exp $

so it's older, and it does have the lpeg.Ca pattern accumulator.

And can I ask one more question about lpeg? Suppose I have the string

"{\em This string is \quotation{heavily} emphasized.}"

and want to transform that into something like

"\color[red]{This string is \quotation{heavily} emphasized.}"

How would I go about this using lpeg? I must use a lpeg.V somewhere,  
but I can't figure out where and how.

Thanks, and all best

Thomas
