I had the opportunity to test Robert's C patch on a recent copy of the
master branch today in a Fedora 28 VM using Gnome3, Xfce4, and KDE5.
Setting the hide argument to `t' in the new Lisp function
`x-set-hide-titlebar-when-maximized' worked as expected in Gnome and
Xfce--the titlebar disappeared when I maximized the Emacs frame.  The
KDE titlebar remained in place except when putting Emacs in fullscreen
mode.
