Identified in 8887e1f697 (r239097413).
9504292b1e9948fb286b1b1cdbe83f66b367b64d accidentally reverted all the
changes that had been made to the weechat wrapper since
8887e1f697d9e13ad277ca7d7054bc42c2459548.
I removed the wrapper, then wrote it again, but this time taking the
code from the latest version of weechat before the bad merge.
