Fix the infinite loop when copying the cursor to the top of the file (#5888)
Example: ``` test testitem ``` Select line 2 with x, then type Alt-C; Helix will go into an infinite loop. The saturating_sub keeps the head_row and anchor_row pinned at 0, and a selection is never made since the first line is too short.
