That patch calls lseek inside write-region on non-regular files as
well, where previously we didn't.  Why is that a good idea?  (It's an
unrelated change anyway.)  This log entry

  1998-06-29  Andrew Innes  <address@hidden>

          * fileio.c (Ffile_regular_p) [WINDOWSNT]: Bind
          `w32-get-true-file-attributes' to t while calling stat.
          (Finsert_file_contents) [WINDOWSNT]: Likewise.
          (Fwrite_region): Don't try seeking to end of FILENAME for
          appending if not a regular file.

seems to indicate that this condition was there for a reason.
