The 4.2 and 4.3 BSD versions of at will fail if you use a shell that
strictly follows the POSIX standard for handling here documents.  Note
that previous documentation of the shell indicated that a here
document could be closed by either the key line or by an end of file.
According to POSIX, an end of file while processing a here document is
a syntax error.

The shell script generated by the stock 4.3 version of at contains the
construct:

$SHELL << '...the rest of the file is shell input'
  ...
Your commands submitted to at
  ...
END OF FILE

With a POSIX conforming shell, all your at jobs will terminate with
syntax errors rather than executed jobs.  The fix to at.c is easy.
Output the line:
...the rest of the file is shell input

just before closing the at queue file.
