Pull request: Fix escaping of paths with spaces

[Jonathon Mah]

Hi folks,

I have a fairly important commit to fix the escaping of tree paths with spaces. Currently, a tree link to a path with a space contains a NUL due to a string overrun! I've changed html_url_path to escape spaces as %20, and left html_url_arg escaping them as +. Someone more experienced needs to check this over.
