When having very long lines in a file, and trying to use tig status the preview of a file breaks when it contains long lines (>2048).
Running on a recent Intel MacBook, installed via brew.
tig -v
tig version 2.5.6
ncursesw version 6.3.20211021
readline version 8.1
Reproduction:
echo 'short line - you should see me' > test.txt
echo -n "freaking long line - i break things" {1..600} >> test.txt
echo '' >> test.txt
echo 'another short line - can you see me?' >> test.txt
tig status with test.txt untracked:

tig status with test.txt added:

Having the line not shown in full might be okay, but dying and not displaying the following rows lead to some confusion here 😉
