If you could give us some background as to why you care so much about the
way Emacs handles a file named "", maybe you'd be taken more seriously.

A file name "" is extrememly rare, so how we behave when facing such
a situation should be driven by the two following goals:
1 - avoid risks (e.g. try not to introduce security holes).
2 - try not to spend too much code&time on it.
I.e. the behavior should mostly be determined by the way the code makes it
work, as long as it makes sense and is not dangerous.
