That's interesting. I'd assumed there was a "Right Way" to do it, and
that it would be whatever coreutil's rm did. If not then we are back to:

This doesn't seem possible without changes at the C level.
Should there be a standard Lisp error for ENOENT?
Currently report_file_errno only does EEXIST -> file_already_exists.
Or should delete-file get a FORCE argument akin to "rm -f"?
