 This appears to be related to terminal emulation settings provided
 by /etc/termcap as cons25 works fine while everything else (xterm*, vt*,
 ans*) all seem to have problems.
 
 On the console (where TERM=cons25), shift+tab works as expected.
 Almost anywhere else -- via ssh for example where TERM=xterm -- shift
 +tab is not recognized/emulated so libdialog gets the leading escape
 character out of the sequence produced by shift+tab (ESC+[Z), and
 therefore it exits the menu.
 
 It should be noted that all libdialog-based programs are effected,
 including dialog(1), not just sysinstall(8).
