patch 9.1.0221: lines following virt text (that fills the window) might be truncated Commit: https://github.com/vim/vim/commit/b6fac4db3647179671d3267a4bcd418e92cd4572 Author: Dylan Thacker-Smith <dylan.ah.smith@gmail.com> Date: Thu Mar 28 11:40:41 2024 +0100 patch 9.1.0221: lines following virt text (that fills the window) might be truncated Problem: The if branch to set `text_prop_follows` was both checking if it was at the end of the buffer text line or if it was at the end of the screen line, but the former being true skipped a guard condition in the latter to only consider 'below' virtual text to follow. `text_prop_follows` being improperly set caused it to skip a conditional block to break at the end as well as one to move `ptr` to the end of the text line, while repeated for each following line of the window. Solution: Move the check for whether 'below' virtual text should follow so it is also used when at the end of the buffer text line.
