Differentiating a substack from a mainstack

[Peter Haworth]

I prowled around the IDE code for the File menu "New substack" item and
here's what happens:

*put* the short name of the topStack into tCurrentStack
*if* the mainStack of stack tCurrentStack is not tCurrentStack *then* *put*
the mainStack of stack tCurrentStack into tCurrentStack
*send* "menuPick" && quote & "New Mainstack" & quote to button "file"
*set* the mainStack of the topStack to tCurrentStack

In other words, requesting a new substack results in a new mainstack being
created then having it's mainstack set to the correct mainstack.
