Fails to write coverage report when there is a space in the project path

If you have a rails app in a path such as ~/Projects/My Project/myapp it appears that the cover_me gem is not able to create the coverage folder, and thus can't create the coverage report. There is no error at any point during the bundle install process or rails g cover_me:install process that would allude to this problem except for a non-fatal error at the end of a rake spec run.

The files /Users/chrisbloom7/Projects/My and /Users/chrisbloom7/Projects/My Project/myapp/Project/myapp/coverage/index.html do not exist.

Notice the how the first path in the error is truncated while the second path is duplicated.

Reproduce this with a Rails app whose path contains spaces, then run rails g cover_me:install and rake spec. Trace how the coverage report paths are assembled from the project path and compare the malformed paths in the error. Done means the coverage folder and coverage/index.html are created at the correct location without truncation or duplication.
