patch 9.1.0121: Infinite loop or signed overflow with 'smoothscroll'
Problem: infinite loop in win_update with 'smoothscroll' set when
window width is equal to textoff, or signed integer overflow
if smaller.
Solution: don't revalidate wp->w_skipcol in that case, as no buffer text
is being shown. (Sean Dewar)
Don't instead reset w_skipcol; that would lose the scroll position
within the line, which may be undesirable if the window is made wider
later.
Also include changes from the splitmove PR #14042 that I (in my infinite
Git wisdom) forgot to commit. This includes a change to
Test_window_split_no_room to ensure it doesn't fail for some screen
sizes.
Move Test_smoothscroll_in_zero_width_window to test_scroll_opt.vim, as
that file feels more appropriate.
closes: #14068
