#1835 subtly changed the semantics of the `LoadFile` plugin hook to no longer have the current script location available for signature files being loaded through `@load-sigs`. This was undocumented behavior, so it's technically not a regression, but since at least one external plugin is depending on it, this change restores the old behavior.
