bug#27357: 26.0.50; Emacs starts fullscreen in Ubuntu 17.04

[Lars Ingebrigtsen]

I'm having a hard time making sense of the code flow in xterm.c.  But
what seems to be happening is that Emacs first comes up with a frame in
proper size, and then it's rescaled to be fullsize.

Looking at get_current_wm_state, in that loop there, a matches both
dpyinfo->Xatom_net_wm_state_maximized_horz and
dpyinfo->Xatom_net_wm_state_maximized_vert, which explains why Emacs
gets maximized.

But I'm having no luck in understanding why those fields are being set,
or where...
