It "can", depending - some people object to the control sequence which
can retrieve the previous value.  I added a push/pop stack for xterm last
year which can work around that (transparently).  I used that in vile
(vi like emacs), and I made a fix for 'screen' which uses it.

For other terminals - some have disabled the objectionable feature,
some have not.  (Some will eventually copy the push/pop feature ;-)
