plt/racket — pull request #615 by greghendershott (2014-04-08 21:27:33+00:00)
Title: Update ,log to handle multiple loggers.

This replaces https://github.com/plt/racket/pull/188.

Given the changes since that was submitted -- i.e. 6.0 moving xrepl from collects to pkgs -- I figured it was simpler and cleaner to make a fresh pull request.

I'll close that old PR and add a comment linking to this one.
