This was because the 'fullboth' terminology is confusing and tricked
me into thinking that 'fullboth' value of the 'fullscreen' frame
parameter means 'fullwidth' and 'fullheight' together.  But in fact,
'maximized' is 'fullwidth' and 'fullheight' together, while 'fullboth'
means the same as 'fullscreen'.  Confusing.

This is now fixed in revision 112048 on the trunk.

This feature is not supported in the Windows build, because I couldn't
find a way of doing that.  (There's a FIXME in w32fullscreen_hook to
that effect.)  Patches to fix this are welcome.
