patch 8.2.4872: Vim9: no error for using an expression only

10 * move.c: Functions for moving the cursor and scrolling text. | |
11 * | |
12 * There are two ways to move the cursor: | |
13 * 1. Move the cursor directly, the text is scrolled to keep the cursor in the | |
14 * window. | |
15 * 2. Scroll the text, the cursor is moved into the text visible in the | |
16 * window. | |
17 * The 'scrolloff' option makes this a bit complicated. | |
