Just for clarity: no, when we are talking about well formatted code,
-S is actually a way better interface.

That's because indentation matters and makes it easy to take in code
structure at a glance, long lines that get cut off by the margin stick
out like a sore thumb already, and lines wrapped at an arbitrary
character are even more distracting to the point of being useless.

In practice I believe the "Silently hiding stuff" concern is much
harder to solve.  In the case of malicious code that opened this
thread, I think a marker on the right margin would reveal the
whitespace more clearly than wrapping that the reader may or may not
notice.

Luckily, it is very easy to switch between the two views on the fly
--- in an already-open "less" window, you just type '-' + 'S'.  In the
spirit of not overriding tool defaults when there is not a strong
reason to do so, I agree that if someone writes a patch to drop
the 'S' I would probably like it.

Agreed ---- a note in release notes and making sure the documentation
reflects the new default should be enough.

Thanks and hope that helps,
