enable and disable submenu items

[Martin Koob]

After more testing I realize what is going on.  The 'enable menuitem'
command places the '(' at the begining of the line that contains the
submenu before the tab which makes it no longer a sub menu.  If you
disable a sub menu from the Menu Builder it correctly places the '('
after the tab and in front of the menuitem's text.

I can get it to work correctly by changing the line in the menu item ie.

put 3 into itemnumber 
put "from target..." into itemtext

if menuaction is "enable" then 
   --enable submenu item 
   put tab &  Itemtext into line  itemnumber of button "File" 
else 
   --disable submenu item 
   put  tab & "(" & Itemtext into line  itemnumber of button "File" 
end if

Doing this will get the correct behavior.  However it would be better if
enable menuitem could handle this.
