Address conflict with default spell-check mappings

[ZeroKnight]

By default, (Neo)Vim uses [s, [S, ]s, and ]S for jumping to words highlighted by the spell-check system. This should be addressed in some way. Some ideas:

• Different choice in mappings, perhaps substitute brackets [|] for angle brackets <|>
  • Alternatively, an option that automatically maps the spell-check mappings to the angle bracket variants
• Different letter choice, perhaps ]j, ]J, ]k, ]K? Not quite as intuitive due to how overloaded and ambiguous bare j and k are as a concept.
• Default to <Leader> mappings
  • <Leader>sj/<Leader>sJ for next/last sign and <Leader>sk/<Leader>sK for prev/first sign?

Working out of the box is an important design choice, so there should be no user requirement to map or remap anything themselves, so unbound by default or any kind of prompt is out of the question.
