hmm... I can see where that would be misleading. in the tex it is
listed as @samp(x) which renders as `x'.  pretty consistent throughout
the help looking elsewhere.  also comes up for @code(stuff).

so where in the source does that live?

second:  this is one of those places where Matlab's 'did you mean...?'
functionality is pretty nice. has there been any attempt to implement
something similar in octave's interpreter to ease (or increase
laziness with) syntax errors?
