Behavior of <space> and <backspace>

[Justin M. Keyes]

With "vim -u NONE -N", given the following text:

ABC
DEF

- With cursor on D, <backspace> moves to C.
- With cursor on D, `h` does nothing.
- With cursor on C, <space> moves to D.
- With cursor on C, `l` does nothing.

Where is this documented? Is this behavior affected by any options?
Note that "vim -u NONE -C" (Vi-compatible) does not behave in this
way.

":help <space>" implies that <space> is equivalent to `l`, which is
clearly wrong. Likewise for ":help <backspace>".

Thanks.

This behaviour is affected by &whichwrap option.

It is not that wrong. Just space and l, as well as backspace and h can
be configured separately by &whichwrap option and Vim defaults make
them behave differently.

Thanks! A mention of |whichwrap| at :help <space> would be intuitive.
