* The write.* functions now return the name of the output file.  This
  is useful if the fname argument is a call that creates the file
  name, e.g. tempfile().  Previously there was (practically) no return
  value.  This should not break anything.
* Examples in the write.*.Rd files were modified to use tempfile()s
  instead of writing to the working directory, which was potentially
  harmful.

Use tempfile() instead of working directory (should have been in the
previous commit).
