This seems a bit weird in a new file (the "reenable" part).
Did you copy this from somewhere?
I would suggest just changing it to "Enabled..."

[jbudorick, 2014/10/16 17:55:07]

Hah, no. This CL was motivated by an offline conversation between mkosiba and I
this morning regarding these tests in particular.

I have no qualms with changing it to "Enabled", though, and will do so in the
next revision.
