S-tab and <backtab>

[Paul Pogonyshev]

It seems that name "backtab" should imply opposite to tab functionality
of S-tab/<backtab>.  In `info-mode' one can use M-tab to go backward
(apart from <p>), but on modern desktops (KDE and Gnome) M-tab is
typically bound to switching between windows and typing <esc tab> is
very inconvenient.  Besides, on the same desktops <shift> is consistently
used for reversing and so S-tab is used as the opposite of <tab>.

Finally, S-tab is used for "going backward" in at least `man-mode' and
`custom-mode'.  So i think the following patch is well justified.
