A Compose sequence whose result is more than one character has no
keysym, so xkb_compose_state_get_one_sym gave nothing and the result was
lost; the UTF-8 the compose state holds is committed instead. Clients
that ask for a StatusNone style — fcitx5 offers them — failed to create
an input context; the three preedit styles come in both status flavours
now. IBus SetCursorLocation returned an error for a negative width or
height that nothing reads and no client ever waits for.
xim/keymap.c held one 37-line function apart from xim.c, with its own
prototype typed by hand in xim.c and nelem spelt out because it avoided
dat.h — all so that a test could link it without imdkit, though the XIM
adapter test #includes xim.c whole anyway. It lives in xim.c now, and
xim.c, the last file of its directory, sits beside ibus.c.
