ident pattern match is incorrect

The git attribute "ident" fails here:

  sed '2,/and the template file/d
      /\$Id:/d
      /Last template edit:/d' getopt-test_${testname}.c

The pattern match for ident should be (shell syntax):

   $'\$Id(:[^$\n]+\$|\$)'

In other words, it is not a multi-line pattern.
I was looking for a bugzilla entry here:
   http://git-scm.com/

but I did not see a bug reporting method.
