This is only used in the current PR to avoid ugly
`strprintf(Untranslated("%s:\n%s"), str, MakeUnorderedList(details)`
boilerplate in init code. But in the future the function could be extended and
more widely used to include more details in GUI error messages or display them
in a more readable way, see code comment.
