How to capture the tags applied by git decorate

What goes on here? Why are the two outputs different?

$ git log --oneline -n1
7dbee6d (HEAD -> master, origin/master, origin/HEAD) some commit msg

$ git log --oneline -n1 | head
7dbee6d some commit msg

The piping to 'head' was the simplest example I could find to illustrate the problem. The problem prevents me from e.g.:

From the log manpage:

--decorate[=short|full|auto|no]

    Print out the ref names of any commits that are shown. If short is
    specified, the ref name prefixes refs/heads/, refs/tags/ and
    refs/remotes/ will not be printed. If full is specified, the full 
    ref name (including prefix) will be printed. If auto is specified,
    then if the output is going to a terminal, the ref names are shown
    as if short were given, otherwise no ref names are shown. 
    The default option is short.

So when called with --decorate=auto, the behavior will change depending whether stdout is a terminal or not. If you pipe git log output somewhere, stdout will not be a terminal.

The default is short, but you may have auto somewhere in your git options.

To get the same behavior in both cases, call it with --decorate=short
