    gchar *gnc_account_get_full_name must be freed
    
    The gnc-account-sel.c one was causing a runaway leak -- leaked
    full_name for every account (except the matched account) in the
    GNCAccountSel. Interestingly the original commit[*] suggests the name
    should have been freed correctly however the braces prohibited it.
