No it doestn't.
Autoconf has an AC_PROG_SED macro which checks for a POSIX sed.
http://www.gnu.org/software/autoconf/manual/html_node/Limitations-of-Usual-Tools.html#sed
Portable sed regular expressions should use ‘\’ only to escape
characters in the string ‘$()*.0123456789[\^n{}’

If I understand that right, POSIX doestn't mandate \t so it wouldn't
help us.
