Fix nonportable sed script in 'missing'.

[Ralf Wildenhues]

Yeah, I actually had to stumble over this recently introduced buglet;
Tru64 sed interprets everything between the first 't' and newline/end
of script as a label, then complains about the label being longer than
6 characters.  :-/

(Of course this is all duly documented in the Autoconf manual section on
shell portability).

Pushed both branches.

Cheers,
Ralf
