Description:

Positional replacement strings appear not to function on any line after the first, even when the replacement string itself is not split by a line feed.

Perhaps this has already been fixed from a similar issue earlier this month. Is there some workaround I could use in the meantime, other than placing all commands on a single line?

Thanks,
