I'd be tempted to leave the SHA-1 to indicate "sometime before" but
delete the author and date (I also think it looks a bit nicer to omit
the opening parenthesis):

    ^cc29195                                           103) 
    7bbc458b (Kyle J. McKay  2014-04-22 04:16:22 -0700 104) test_expect_...
    ^cc29195                                           105)         test...

On a slight tangent, I tried this in a fairly young repository and got
this (with master at v2.0.0-rc2-4-g1dc51c6):

$ git blame Makefile | head -5
7a3fc144 (John Keeping      2013-12-26 17:37:53 +0000   1) REL_VERSION = v0.2
5c9829f9 (John Keeping      2013-07-29 17:03:26 +0100   2) 
5c9829f9 (John Keeping      2013-07-29 17:03:26 +0100   3) # The default target 
is...
^f7fae99 (John Keeping      2013-03-24 17:14:40 +0000   4) all::
^f7fae99 (John Keeping      2013-03-24 17:14:40 +0000   5) 

f7fae99 is the initial commit in the repository, so shouldn't the last
two lines blame to that, not a non-existent ancestor?
