LGTM
maybe add a comment explaining that tins a requirement of term-ansi-color which is in turn a requirement of coveralls and 1.6 release is required until we switch to a Ruby 2.0 compliant JRuby ?

this is such a straightforward fix I am comfortable with a quick merge, plus I am stumbling on this now :P

+1 will update the PR with the comment.

@colinsurprenant concerning the comment where do you want it? In the Gemfile there is risk it will be removed?

# If you modify this file manually all comments and formatting will be lost. :)

[colinsurprenant]

its not a problem, the comment will be in the repo, it will be lost when executing plugin manager commands but that's not important. what's important is that we have the comment in the source tree repo so that when we modify and look at it we understand what's going on
