Module Name: src

Modified Files:
src/usr.bin/make: var.c
Log Message:
make: document interaction between cmdline and global variables
Make prevents global variables from being or becoming visible when a
command line variable of the same name is already defined.
There is a double safety net here. Even if the call to Var_DeleteExpand
were removed, there would be no noticeable effect, other than one less
line in the debug log.
No functional change.
