After certain 3-step manipulation with tabs, can't quit vim with :q!. (vim 7.0.42). Tabline is not updated properly.
% vim -u NONE -U NONE ix<esc> " make 1st buffer modified :tabnew<cr> " create 2nd tab ix<esc> " make 2nd buffer modified :tabclose! 1 "delete non-last tab " ^^^ watch the tabline after tabclose command. " PROBLEM #1 here: tabline shows 2 tabs but this is " wrong; only 1 tab exist at this point :tabs " confirm that ony 1 tab exists :q! E37: No write since last change (add ! to override) E162: No write since last change for buffer "[No Name]" "^^^^^ PROBLEM #2: can't quit vim here, must resort to kill Yakov
