The '-trailing-space' syntax to disable the trailing-space setting is
not obvious and not documented as far as I can see. I would have
assumed a value of '' would disable it.

Is there a documentation bug here? If so, I suggest this patch. I
didn't find anywhere else where the '-setting' syntax was used to
disable something.

Doesn't gitattributes(5) describe the overall syntax in detail?

Yes, but as Peter says in his reply to you, it only talks about [-!]name
syntax to force the variable to unset (with '-' prefix) and to revert the
variable to the unspecified state (with '!' prefix).

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.  We would certainly need to clarify that.

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