Comment # 1 on bug 994486 from Michael Vetter

Thanks for spotting this.

shadow.5 was provided in man-pages in the man-pages-addons.tar.bz2 as you said.
Maybe shadow didn't ship its own manpage at that time and later on they decided
to still use the one from man-pages.

I checked revision 97 of openSUSE:Factory/man-pages to see which other manpages
have been previsously provided in man-pages-addons.tar.bz2.
The following ones where in that tarball and all of them have been migrated to
the main tarball.

iconv.1 -> man-pages
notify_init.2 -> man-pages
fanotify_mark.2 -> man-pages  
name_to_handle_at.2 -> man-pages 
open_by_handle.2 -> man-pages

SR#427510 to Factory.
SR#427511 to Leap 42.2.
SR#427552 to Leap 42.1.
