Assuming the user has not changed any escape sequences via resources
settings, is this still really the case?

On my (Debian x86) system, xterm and gnome-terminal (which gives $TERM
as "xterm") seem to agree on a quasi-standard set of escape sequences
for function-keys modified by shift, control, alt, shift-control and
shift-alt, all of which are distinct.  But in term/xterm.el, only the
unmodified function-key escapes are translated.  Is there a good
reason for this absence?  Are the escape sequences for modified
function-keys in fact different in xterm from system to system?  Is it
really true that life is messier than it seems on my system?

I am aware that the escape sequences for rxvt and rxvt-derived
terminal emulators are completely different, but again term/rxvt.el
translates some of these -- including control-modified function keys
-- but not all, such as shift-control modified function-keys.  Again,
is there a good reason for this omission?
