[Bug 1965972] Re: shim doesn't boot boot entries without spaces/zero characters in optional data

[Dimitri John Ledkov]

given how cryptic optional data parsing in shim, I am not surprised.
last time I tried to figure out how to make it work, I failed.
so somewhat this sounds right that a space helps.
