I just happened to notice the lack of "^" while reading through that Brian Kernighan tutorial PDF I linked to, figuring that the minimally invasive patch would keep GNU ed(1) historically accurate. That said, I acknowledge it's an obscure & non-required corner and I don't really have any investment in "^" beyond ensuring that those historical documents continue working. -Tim _______________________________________________ bug-ed mailing list bug-ed@gnu.org https://lists.gnu.org/mailman/listinfo/bug-ed
