Ok, I stand corrected. Last version of 'w' which shows hostnames by
default seems to be 3.3.3 they put in wheezy:

First, wheezy's 'w' did not have '-i' option at all.

Second, wheezy's debian/rules contains this '--enable-w-from' configure
option that I missed:

override_dh_auto_configure:
    ./configure \
      --build=$(DEB_BUILD_GNU_TYPE) \
      --enable-watch8bit --enable-w-from \
      --enable-skill \
      --prefix=/usr \
      --exec-prefix=/ \
      --libdir=/usr/lib/$(DEB_HOST_MULTIARCH)
