Fix spacing inoconsistencies which conflict with style guide

This is also so that Hound can be introduced without it bugging
people about issues in existing code.

If git-blame brought you here you may want to read this, the
problem is with git-blame, not this change.

Try running these two lines just once:
``
git config --global alias.praise 'log -p -M --follow --stat --'
git config --global alias.praise-line 'log -p -M --pretty=format:"%h (%an %ai)" -L'
``

Now in future you can use

`git praise <path/to/your/file>`

or if you want to see the evolution of a specific line or range of lines

`git praise-line <start-line>:<end-line>:<path/to/your/file>`

Some examples you should try:
``
git praise lib/awesome_print/version.rb
git praise-line 8:8:lib/awesome_print/version.rb
``
