Set the caret offset after stripping spaces back to original offset

[iromli]

This is sort of feature request for current implementation.

Currently, caret offset returns to 0 after stripping operation (without blocking the selected text). Perhaps, this one occurs only if the input scope is :document. This is pretty annoying when we have cursor, for example, at L500 and we need to stay on that line. It would be nice if cursor is set to the original offset back.

Any plan to implement this one?
