lv.el: Update truncation rules
* lv.el (lv-window): Defer `truncate-lines' to `lv-message'. Set window
hscroll to 0, just in case.
(lv-message): If STR is one-line, set `truncate-lines' to nil, otherwise
set it to t. Make `window-min-height' buffer-local and set it to the
amount of newlines in STR.
Re #40.
