Comment 5 for bug 573834

"Source" is less exclusionary toward other things such as text, diagrams, etc. than "Code" is. You can think of your files as being the "source" of your document, image, etc.. It is also more alike the other major code-hosting sites per my previous comment.

However, "Code" is definitely an improvement in my book over "Branches" so I won't complain again if you don't see the wisdom of "Source" after reading this comment. :-)
