Wow! My mystery is solved. Every once in a while this would happen to me.
About as often as I'm forced to edit a script on a system with MS-DOS in
its family tree. I never made the connection and hadn't thought to examine
the file contents itself. I usually just nuked it and started over. And
all I needed was a quick,

tr -d "\r" < f1 > f2

Or, if you prefer Perl,

perl -pi -e 'y;\r;;d;' f1

Thanks for explaining it.
