Isn't his config somewhat broken?  It looks like this:

  last = "!f(){ since="$1"; shift; git lg --since=\"last $since\" "$@"; }; f"

Those interior double-quotes should all be backslash-escaped. I didn't check, but git should interpret this as:

  !f(){ since=$1; shift; git lg --since="last $since" $@; }; f

which is probably not quite what he wanted (the quotes around $1 were actually superfluous, but the ones around $@ are important).

That being said, I think it is intentional that the value is not just "a single double-quoted chunk" but rather could consist of several quoted (or unquoted) chunks concatenated together. What does your parser think of:

  [foo]
    bar = "foo"bar"baz"

It should be:

  $ git config foo.bar
  foobarbaz
