This is a usability issue.  If upstream thinks they have to do such a
potentially destructive and backward-incompatible change for no other
reason than "is not in POSIX", they can do so, but there's no good
reason the distros who *care* for usability have to do this either.

Right, Debian and OpenSuSE revert the change and the BSDs will not break
e/fgrep either, obviously.  I doubt Ubuntu will do that.  Fedora often
values progress, for a given value of "progress", higher than usability.
They will probably see lots of Bugzillas and user requests in other
forums due to this change and then ignore them.  But that doesn't mean
we have to do it.

Again: Egrep and fgrep are used in lots of scripts around the world.  A
change like this will have a massive impact for years to come.

So, again, in the name of usability, let's follow Debian and OpenSuSE
here, not Fedora, please.
