[PATCH 3/6] rebase -i: emphasize that 'update-ref' expects a fully-qualified ref

["SZEDER Gábor" <szeder.dev@gmail.com>]

The argument of the 'update-ref' instruction is treated as a fully
qualified ref, and there is no DWIMery to interpret 'update-ref
feature' to create/update the branch named "feature", i.e. the ref
"refs/heads/feature".  Update the help text appended to the todo list
to make this clearer.
