Always collapse jumps in exec/eval, remove -collapse-jumps switch

There does not seem to be any reasonable use cases of not collapsing
jumps when the input is not comming from the user. Always collapse
them.

It could make sense to move jump collapsing out of context_wrap as
in general any action not comming directly from the user should
collapse them, at the moment a comment or mapping will not collapse
jumps, which is unfortunate.
