Numerous problems with this patch:

(1)
  CC      coreutils/tac.o
cc1: warnings being treated as errors
coreutils/tac.c: In function 'tac_main':
coreutils/tac.c:40: error: assignment discards qualifiers from pointer
target type
coreutils/tac.c:45: error: implicit declaration of function 'sed_main'
make[1]: *** [coreutils/tac.o] Error 1

(2) unfreed malloc data in sed_main will make memory usage grow
with "tac <many files>" invocation.

(3) tac is NOEXEC, sed isn't. Calling sed_main from tac_mian is unsafe

It also had some problematic parts.
I fixed it up and just committed it to git.
