[PATCH v3 3/4] rebase: fix an incompatible-options error message

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

When the user specifies the apply backend with options that only work
with the merge backend, such as

    git rebase --apply --exec /bin/true HEAD~3

the error message has always been

    fatal: --exec requires an interactive rebase

This error message is misleading and was one of the reasons we renamed
the interactive backend to the merge backend.  Update the error message
to state that these options merely require use of the merge backend.
