Description of problem:
I'm (once again) busy trying to make all the x terminal emulators behave
identical. One of the problems is that xterm, gnome-terminal and konsole behave
different for cursor and/or function keys with modifiers (alt, ctrl, shift)

Short story:

The attached patch brings xterm fully-inline with gnome-terminal and partial
inline with konsole, the rest needs to be fixed in konsole, I know what I'm
doing so just apply it :)

Read below for the long story:

For the function keys gnome-terminal and konsole seem te agree on how the
modifer keys should be reported to the application, xterm also has identical
behaviour once you remove the shift + function key bindings override from the
XTerm app-defaults resource file. With these removed the only difference between
the 3 term. emulators is that xterm seems to ignore the alt modifier.

The attached patch for the XTerm app-defaults file removes the shift F-key
bindings and adds alt F-key bindings mimicking gnome-terminal and konsole with
this patch applied the F-key behaviour for all 3 terminals is identical.

The cursor keys are a different story, xterm and gnome-terminal both have
different ways of reporting these to the application whereas konsole just
ignores them.

The attached patch makes xterms behaviour identical to gnome-terminal,
because:
-I think gnome-terminals way is technically better
-gnome-terminal is the default terminal in a default RH setup, so I would rather
not touch it
-some applications already expect the gnome-terminal way of reporting mod-keys.
Try this for example:
-start gnome-terminal (with just plain bash)
-type "touch aap noot mies" (and do not press enter!)
-use ctrl-left and ctrl-right to walk through the words on the cli
-now try the same in xterm.
