Explain that dangling means untagged leaves (<none>:<none>), and that dangling=false still includes repo:<none> images, which often look \"untagged\" but are not dangling. Fixes docker#4159 Signed-off-by: Dean Chen <862469039@qq.com>

People expect `dangling=false` to hide every untagged-looking image. In practice it only drops true dangling leaves (`:`); images that still have a repository but no tag stay in the list.
Documented both sides of the boolean so that difference is obvious.
Fixes #4159
