This change isn't needed, and the compiler will check that we have it
init'd.
It *is* needed when combined with your 3/5, but even then it's the wrong
solution. In that change you move the commit_notes() into that "if"
branch that needs the "logmsg", and it's correct that you need to
NULL-init it to safely pass it to free().
But let's just declare the "logmsg" in that if block then, and move the
free() over there, that reduces the scope it's in.

This change is good, but then let's change the other such case in this
file to a designated init too, and make the commit message etc. be about
using designated init here.
