What does "adding command lines to grep" mean, concretely? It isn't clear to me. I think what is being refered to is that the commands egrep/fgrep are considered deprecated infavor of using "grep -E" and "grep -F" directly. GNU grep did not add those command line options to solve "similar issue" though. Why they added it is of a entierly different nature, namley POSIX requires it and most Unix grep have it.
