What does a return statement mean within a module's body, but not within ModuleApply, ModuleLoad, or ModuleUnload procedures?

Is the disappearance of the return line, and the u:=3 line that follows it, some sort of automatic simplification? I'm not even sure what such a return statement is supposed to mean, in a module's body but not in ModuleApply et al.

> module() local u; u:=2; return; u:=3; end:
> convert(%,string);
"module () local u; u := 2; end module"

When I mention automatic simplification here I mean things like the disappearance of the if..then..fi for the following procedure creation. I also wonder where in the help-pages that simplification is documented.

Maple 11.00, Standard GUI, worksheet mode.

plot(sin(x),x=-10..10,legend="__never_display_this_legend_entry");

It's magic. The LEGEND() call is present in the PLOT structure, but it doesn't get displayed.

It's unfortunate, how the "Recent Comments" summary is now so far down the right hand side column that it isn't visible without scrolling down.

Is there any way to customize it (when logged in, say), to get the more interesting content right up at the top where one can see the summaries without having to scroll down?

The first example below seems OK. But, should I be expecting the different behaviour in the second example?
