A (very) minor correction: Command-line variable assignments override 
even "="-style ones:

$ cat Makefile
OMG=    OH MY GOD

.error ${OMG}
$ make
"/home/ab/Makefile", line 3: OH MY GOD
$ make OMG=OMIGOD
"/home/ab/Makefile", line 3: OMIGOD

But "="-style assignments does nullify overrides stored in src.conf or 
make.conf, so I believe your overall point is still quite valid.  : )

Cheers,
Eugene
