add-patch: improve help for options j, J, k, and K

The options j, J, k, and K don't affect the status of the current hunk.
They just go to a different one.  This is true whether the current hunk
is undecided or not.  Avoid misunderstanding by no longer mentioning
the current hunk explicitly in their help texts.
