Doesn't remove space from %w array

[guyisra]

for an array defined like
%w( 2016-04-01 2016-03-01 2016-02-01 2016-01-01)

Rubocop won't fix the initial space (or add a space at the end)

Using latest rubocop

I think the best solution is to add a new cop for space in %w/%W literals, and one for %i/%I.

@jonas054: Do you think it would be acceptable with a single cop for both types of word array (%w and %i)? Since most of the functionality will be duplicated. For example Style/SpaceInsideWordArray? (Arguably, Style/SpaceInsideBrackets should be named Style/SpaceInsideArrayLiteral. 😀 )

Also, do we want to include a configuration option to enforce spaces? I.e.:

%w( 2016-04-01 2016-03-01 2016-02-01 2016-01-01 )

[jonas054]

Yes, that would be acceptable IMO. And let's only enforce "no space", and maybe add the configuration option later if there's a demand.
