Space in url for download of python sources prevents download of python sources.

[callahanp]

in commit 8459aea
Because the url now contains a space in the version directory, the fetch gets the directory https://www.python.org/ftp/python/ instead of the intended 2.7.10/Python-2.7.10.tgz. gzip fails because the directory listing is not the intended tgz file.
Test results and patch included.
