It would be sad to lose this helpful feature, but there are too many
problems with weird behavior in buffers with long-line-optimizations.
For example, when there is at least one long line near the end of
a diff-mode buffer, then sometimes the buffer gets truncated,
'diff-hunk-file-names' returns nil on diff headings,
and there are a lot of such errors in the Messages buffer:
Error during redisplay: (jit-lock-function 1) signaled (args-out-of-range #<buffer *vc-diff*> 1118 1370)
...
Maybe it's still possible to fix this?
