When "git describe C" finds an annotated tag with tagname A to be the best name to explain commit C, and the tag is stored in a "wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the command gave a warning message but used A (not B) to describe C. If C is exactly at the tag, the describe output would be "A", but "git rev-parse A^0" would not be equal as "git rev-parse C^0". The behavior of the command has been changed to use the "long" form i.e. A-0-gOBJECTNAME, which is correctly interpreted by rev-parse. * jc/describe-misnamed-annotated-tag: describe: force long format for a name based on a mislocated tag
