thank you for clearing that up!
Aha, I see. I've read that part about "strictly textual" and "performed
before all other expansions" in the manual, but I didn't realize all the
consequences. This means that my quotes get interpreted *after* the
brace expansion is done, right? As a result, a call like
echo "$(echo "{1..3}')'
ends up as
echo "$(echo "1')' "$(echo "2')' "$(echo "3')'
and that surely won't work.
This makes a lot more sense now.
Thanks again,
Peter
