Strip colorized diffs, show line numbers in context
Summary: - When users pipe in colorized diffs, strip the colors instead of failing. - When showing context, show line numbers (we do show 3 lines around the failure, the failure was just on the first line). - Remove an irrelevant TODO comment (we handle this elsewhere now). Test Plan: Unit tests. Reviewers: Makinde, btrahan Reviewed By: Makinde CC: aran, epriestley Differential Revision: https://secure.phabricator.com/D1887

// - You piped a colorized diff into 'arc --raw' or similar (normally

// - You're diffing a file which actually contains ANSI color codes.

// two cases by testing for a color code at the beginning of a line. If
