It works regardless.  The GNU Sed manual says:

`$'
     It is the same as `^', but refers to end of line.  `$' also acts
     as a special character only at the end of the regular expression
     or subexpression [...]

Is this a GNU-specific Sed extension?  (I don't mind making it more
portable, even if it is, although DJGPP uses GNU Sed.)

Thanks.
