* This code serves two purposes:
|
|
*
|
|
* (1) Flattening 'if' blocks, which do not specify a submenu
|
|
* and only add dependencies.
|
|
*
|
|
* (Automatic submenu creation might still create a submenu
|
|
* from an 'if' before this code runs.)
|
|
*
|
|
* (2) "Undoing" any automatic submenus created earlier below
|
|
* promptless symbols.
|
|
*
|
|
* Before:
|
|
*
|
|
* A
|
|
* if ... (or promptless symbol)
|
|
* +-B
|
|
* +-C
|
|
* D
|
|
*
|
|
* After:
|
|
*
|
|
* A
|
|
* if ... (or promptless symbol)
|
|
* B
|
|
* C
|
|
* D
