The problem is that grep keeps linked against libpcre and it can cause
problems like pointed in referred bug report, and it's really risky as
people can have their portage completely broken for example when libpcre
is downgraded for some reason. That doesn't sound like a good *default*
behavior for me

Of course, other option would be to default to "-pcre" for grep only (by
default), but I don't know if we really want every package to have pcre
by default...
