I've been editing .config or doing 's/.*CONFIG_FOO[= ].*/CONFIG_FOO=y/'
on it for a decade before that. With all the same limitations as
all.config, and my new CONFIG_FOO=y command line support.

How do *you* quickly, from the command line, enable or disable a single
option in an existing config?

That's a reasonable concern, but I think it's misplaced in this case.
We're not enabling anything that we're later going to break. I can't see
many people *depending* on the fact that 'make CONFIG_SATA_MV=y
oldconfig' actually does *nothing* in some cases.

When we later, hopefully, get proper dependency resolution, that will
take something that *wasn't* working and make it work. For all.config
and for the command line overrides (and in other places) at the same
time.
