236157 (Teach git-describe how to run name-rev, 2007-05-21) introduced
`git name-rev --name-only`, with the intent of using it to implement
`git describe --contains`. According to the message, one of the primary
objectives of --name-only was to make the output of name-rev match that
of describe.
$ git describe --contains --all master
master
$ git describe --contains --all master~1
master~1
$ git describe --contains --all v1.8.3~1
v1.8.3~1
$ git describe --contains --all v1.8.3
v1.8.3^0
The last invocation unnecessarily prints a trailing "^0" (--stdin does
not suffer from this defect). Fix this.
