Indentation - usually, an operator is intended to the column after the
containing ( on the line above.

Do we really need a function for this, or can callers just call g_free
directly? But it doesn't hurt to have the layer of indirection,
especially if we might be freeing more than one thing in the future.

Indentation - 'list' should start on the column after the containing (
on the line above.
