Re: [PATCH] Document disabling core.whitespace values trailing-space and space-before-tab

Junio C Hamano [off-list ref] writes:

Various "values" given to the whitespace attribute actually act as if they
are sub-variables and obey the similar "[-]name" rule, but (1) that is
left unsaid, and (2) in that context '!' does not make sense so only '-'
has any meaning.

Actually I take it back.  "!name to revert to unspecified and -name to unset"
really is about name; values to whitespace do not work like "sub-variables"
at all.

So I think Peter's patch is going in the right direction.

I've committed a much more simplified version.
