Allow spaces between arguments in Rake task

[samzhang111]

rake my_task[arg1, arg2]

fails with

Don't know how to build task 'mytask[arg1, '

I think this is a pretty big gotcha. It would be nice to support spaces after commas.

As a workaround, use quoting in your shell: rake "my_task[arg1, arg2]"
