They are supported on FreeBSD actually.
wc -L since FreeBSD 7.2 and sed -r since 8.1.
OS X's tools are older than that.

Maybe in future.

-e came from http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=811627be
I think it was a typo actually as -e was only for HP/UX compat,
and is even ignored now on that platform.

I pushed this gnulib change to fix it, which we'll pick up on next sync:
http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=d5e367c5
