docs wanted?

[ernst]

Hello all,
i am currently writing an octave parser based on reverse engineering.
By doing so, I found some gaps in the octave manual http://www.gnu.org/software/octave/doc/interpreter/index.html.
I think a manual shall be comprehensive and I would like to contribute a little.

Let me know, whether you are interesting.
Some items I found: missing in description of

• function declaration: parameters with default values, variable parameter lists
  
• for comments: in "-comments, " need not be escaped: also "" is a way: "He said ""Hello"" to all of us" works perfectly. Accordingly for '-comments. 

Greetings,

Ernst
