Fix RST formatting error preventing uploads to Pypi

Because of an extraneous space in the HISTORY.rst header for 0.2.4, the
file fails to parse with the following error:

<string>:50: (WARNING/2) Block quote ends without a blank line; unexpected unindent.

Because we use both the README and the HISTORY file in the
long_description package information, Pypi rejects the upload. This
fixes this.
