Inspired by

http://stackoverflow.com/questions/7487778/could-you-tell-me-what-this-error-means

I wrote the following very small (one-line) patch which returns an *informative* error message when R tries to load a zero-byte file rather than

Error in if (!grepl("RD[AX]2\n", magic)) { : argument is of length zero

  I would guess that error messages with the word "magic" in them would be disturbing to new users, who are probably worried already that R is magic ...
