description:
make(1): inline MakeAddChild into ExamineLater

This gets rid of a few void pointers and unspecific variable names like
"l" for the list that should have rather been called "examine" all the
time.

Add quotes around placeholders in debug messages.  Especially for targets
like "all" the message had been syntactically misleading.
