I know that vim understands CRLF (DOS/Windows) EOLs (it wouldn't
surprise me if nano does), so when it opens a file with them it just
accepts that as the way all lines should end in that file.

This is one reason I like using the basic "nvi" version of vi, rather
than vim. That way I see the "^M" throughout the file, and can then
delete them all with:
  :%s/^V^M//g
(where ^V^M is control-V control-M)

There's also a strong argument for creating and editing scripts on a
Unix/Linux machine. :-)
