vim-patch:8.2.4591: cursor line not updated when a callback moves the cursor

Browse Source 
Problem:    Cursor line not updated when a callback moves the cursor.
Solution:   Check if the cursor moved. (closes vim/vim#9970)
e7a74d5375

redraw_after_callback() is N/A. Nvim handles timers on the main loop.
