You're right, I'm wrong, and I hereby resign.
perl -p -i -e "redo if /^\s*$/" file.ext
is completely wrong, as the redo doesn't pull in the next line from the
input. It simply retests the same blank line indefinitely. The neater
perl -p -i -e "s/^\s*$//" file.ext
is the correct way.
Apologies to all,
