Mismatch between actual and documented defaults for g:targets_pairs

[noahfrederick]

The documentation reports the following as the default:

let g:targets_pairs = '()b {}B [] <>'

But as implemented, it is:

let g:targets_pairs = '()b {}B []r <>'

(The former seems like a better default, as the ir/ar text objects conflict with https://github.com/nelstrom/vim-textobj-rubyblock.)

Well spotted! Should be fixed now.
