Subject: [PATCH] engine: an emoji query shows as typed and Space picks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The emoji search folded the keys for its lookup and then showed and
committed the folded copy: SMILE became smile in the text.  And it
showed the transliteration only while that alone matched, so a Korean
query flipped between 웃 and key soup as it grew.  Now the query shown
is the keys while they match anything, else what they type in the
current language, both as typed; only the lookups fold.  Space in a
search picks the highlighted result as Enter does, instead of adding a
space no alias needs.
