in app-editors/xemacs-21.5.34-r4: einfo "*************************************************" "Note: It is a policy violation to use any of these functions to display a line of characters (a banner header). The use of colours and special leading characters provided by these functions is sufficient to make a message stand out." https://devmanual.gentoo.org/ebuild-writing/messages/index.html
Thanks for bringing this to my attention. The banner header in einfo has been removed from the xemacs-21.5.34-r4.ebuild.
