Add -wpc (with parents' children) parameter

[worksofliam]

-wp makes it generate a makefile that includes parents, but also includes the parents' children and their children - this is way too much for simple builds.

We need a new parameter, -wpc, which determines if parents children should be included in the build.

Below is a message from me to a customer about this issue:

I was able to recreate it easily:

But, -wp (with-parents) does solve the problem partially – which makes sense, because the markdown repo includes the impacted parents by default.

The issue is that -wp is including the children of each parent. Here is the makefile with -wp:

all: .logs .evfevent library $(PREPATH)/NEMP.FILE $(PREPATH)/NEWEMP.PGM $(PREPATH)/DEPTS.PGM

Notice that the objects in all match the markdown. But, now the dependency list comes in:

…
$(PREPATH)/DEPTS.PGM: $(PREPATH)/EMPLOYEES.PGM $(PREPATH)/NEWEMP.PGM $(PREPATH)/DEPARTMENT.FILE $(PREPATH)/DEPTS.FILE
…

It is actually including the children (the required objects) to build each object, which is way more than what the markdown provides.

I will have to see about adding an additional parameter on whether to include these or not.
