### I had to run these with as.fun=data.table and skip testing of
### lines$text.before to make them work on githubs different
### arcitectures. I am not sure if the data.table step is needed, but
### I think it was. Inserted this to drop testing text.before.
##   res1$lines[,text.before:=""]
### the reg expressions must evaluate differently on different architectures
