Description of problem:

Typing "help doc" under octave returns:

 -- Command: doc FUNCTION_NAME
     Displays documentation for the function FUNCTION_NAME.  For
     example, if you want to see the documentation for the Octave
     random number generator `rand', type
          `doc rand'
...

but typing:

doc rand

returns:

parse error:

  syntax error

>>> doc rand
...

Version-Release number of selected component (if applicable):
2.9.5-3.fc5

How reproducible:
Always, and more...

Steps to Reproduce:
1.
As above
2.
3.
  
Actual results:
Error is reported.

Expected results:
The documentation should be displayed.

Additional info:
Well, "doc" is a function and must be called as:

doc('rand')

in order to operate properly. In fact the above line works fine.
Of course, "doc rand" would be much better, less and easier typing,
and conformant to the help.
