Yes, I understand. I still don't like it very much. But if many
users will complain, we might change that before Emacs 29 is released.

No, I said making the type of the struct member current_x a ptrdiff_t
or intmax_t will affect performance. The above doesn't propose any
such changes, it just enlarges the "infinity" value. With that value,
lines up to (/ (expt 2 31) 20) => 107374182 (i.e. about 107 million
characters) per line will still display correctly with truncate-lines
when hscrolling is required.
