I tried these pseudo-codes, but these are just 1 time thing and won't
change over time...couldn't figure out a good way.
;if more than one tab, don't hack
if tabpagenr("$") > 1
unmap gt
unmap gT
;otherwise , if there is one tab, use gt,gT,Ngt to switch between buffers
else
if v:count == 0
map gt :bn<cr>
map gT :bp<cr>
else
map gt :<C-U>exec "b" . v:count<cr>
endif
endif
