A complete Japanese reading showed its candidates with the first row
highlighted, yet Enter committed the reading unless the user had moved
to a candidate: the highlight lied. Now sel is -1 while nothing is
chosen, and it alone says what Enter commits; candidatechosen goes.
Every key that ends a composition — Enter, Tab, a language switch, a
special key, a modifier chord, typing on — now commits the chosen
candidate through one flush; before, only Enter and Tab did, and Ctrl+S
after choosing 漢字 committed かんじ.
Space in a Japanese mode is the conversion key, as in every other
Japanese IME: it steps through the candidates (Shift+Space backwards,
both wrapping) and commits a reading that has none, without typing a
space. Backspace and Escape on a chosen candidate go back to the
reading first. Tab in a search wraps through the same cyclekouho.
reset() no longer forgets the caret: a chosen candidate confirmed by
typing on would otherwise redraw the next reading at the pointer.
