I'm not able to upgrade to 3.6.2 yet. But I have upgrade it to 3.4.0.
"deblank(help('help'))" works, but "deblank(help())" does not. Would
you please check the latter one and see if works on 3.6.2 so that I
can decide whether I need to upgrade to 3.6.2? Thanks!

/tmp$ cat test.sh
#!/usr/bin/env bash

/opt/local/bin/octave -q << EOF
%deblank(help('help'))
deblank(help())
EOF

/tmp$ ./test.sh

  For help with individual commands and functions type

    help NAME

  (replace NAME with the name of the command or function you would
  like to learn more about).
