Issue description

Section "Managing Image Streams and Tags" incorrectly states that an existing image stream can be updated by running

$ oc import-image myimagestream[:tag] --confirm

While the command does work without complaints even if --confirm is included, it is undesirable to do so as a typo in the image stream (or istag) name will inadvertently create a new image stream (or istag) when infact it should fail.

The --confirm option is only needed if a new import location is to be set for an istag:

$ oc import-image --help
...
    --confirm=false:
        If true, allow the image stream import location to be set or changed
