I disagree.  The documentation is already asserting “DocPad is for people who know `git`”, so why would people who already know `git` need a link to Git’s homepage?

Moreover, formatting command-line items in monospace tends to improve the skim-ability of documentation.  Wherever possible, (technical) documentation should be skimmable; it should never force someone to read everything sequentially until they find what they were looking for.  

(In this specific case, the formatting isn’t likely to be helpful.  But I do it anyway because I want to be consistent with my practices elsewhere in the documentation.  Consistency is the foundation of all good technical documentation.)
