loader.efi: "Malformed line (27)" error apparently due to recent splash config entry

I just updated one of my systems (an AArch64 ADLINK Ampere Altra Dev 
Kit) to the latest -CURRENT and copied the latest /boot/loader.efi into 
/boot/efi/efi/freebsd/loader.efi and /boot/efi/efi/boot/bootaa64.efi and 
noticed a new message during boot, apparently introduced in this commit?

     loader: default: Add a default splash screen

     Setting boot_mute="YES" currently use the in-kernel black and white 
logo.
     Instead default to the color png one.
