BANG! BING! BOOM! What a great reply. You see this? This is why Perlmonks is not dead, contrary to rumors.

but the carriage returns remained in the data, causing the cursor to return left and overwrite the text again and again

You know, at some point I got suspicious about the data but I couldn't visualize it doing that, so I dismissed that train of thought. What I eventually came up with (above) was partly dumb luck :-).

I totally get it now, thanks. Consider me educated by your demonstration of xxd, which I'd forgotten about.

What I've decided to use for portability is:
</dev/clipboard perl -0777 -e 'my ($l)=<>; $l=~s{\cM?\cJ}[ ]g; print $l;'

or, in your more terse and idiomatic perl:
perl -pe 's/\cM?\cJ\z/ /'

That should DTRT on either *nix or MS Windows, right?
