unfortunately not.  in this case, ie. with backup-by-copying set `t'
and tramp in place of ange-ftp, i don't get asked for a password at
all (surely because i have it in a ~/.netrc), but saving the edited
file fails.  here's the backtrace, which still contains bytecode.
just load-library "files.el" didn't help any (i wonder why).

saving-by-copying has been double-checked!
