The SysV solution.  Not all echo's interpret \r.  Portable (I think):
	<input sed s,'$',`echo a | tr a '\015'`, >output
If your system + shell allow quoting through ^V:
	<input sed s,'$',^V^M, >output
(here ^V is ctrl-v, ^M is ctrl-m or return).  BSD and BSD derived systems
do allow ^V quoting in general, but not with all shells.  A notable exception
is the Korn shell.  How do I quote a return in the Korn shell?
