Highlight in visual mode from current cursor position on

In visual mode, hitting iv should highlight up to the next punctuation mark from the current cursor position, and not from the position where visual mode was entered.

This seems related to https://github.com/beloglazov/vim-textobj-punctuation/issues/3 so perhaps one should ask @kana about it?

Start by reproducing the issue in Vim visual mode with `iv`, comparing the result when visual mode begins at a different position. Check the related vim-textobj-punctuation issue for context. Done means highlighting extends to the next punctuation mark from the current cursor position rather than the visual-mode entry point.
