Just for the record: I believe that \{1,\} might be portable.

As usual, <URL:info:autoconf#Limitations%20of%20Usual%20Tools> (aka as
(info "(autoconf) Limitations of Usual Tools")
) provides a real horror show of sed variants.

Actually, one can get the cursor right on the spot by typing
info autoconf      (or the respective Emacs command C-h i g (autoconf))
i sed RET

There is something to be said for well-indexed documentation...
