+ *v:echospace* *echospace-variable*
+ v:echospace Number of screen cells that can be used for an `:echo` message
+ in the last screen line before causing the |hit-enter-prompt|.
+ Depends on 'showcmd', 'ruler' and 'columns'. You need to
+ check 'cmdheight' for whether there are full-width lines
+ available above the last line.
+
*v:errmsg* *errmsg-variable*
v:errmsg Last given error message. It's allowed to set this variable.
