[doc] One word missing from int8 help string.

[Francesco Potorti`]

I suppose that the missing word is "Octave", as per the patch below.

I also suppose that this change does not require a CnageLog entry.

By the way, how do I convince hg to generate export diffs using the -pb
option to 'hg diff'?
