* 21890: Src/builtin.c, Src/prompt.c, Src/zle_utils.c: allocation
inconsistencies in print builtin, segmentation error with
left prompt truncation from 21882, warning about variable
signedness in zle_utils.c.
* 21887: Src/Zle/zle_refresh.c: attempt to display wide characters
wider than one screen cell properly.
