README.markdown / ASDF issues

[slyrus]

The README.markdown file contains some non-ASCII characters which cause the read-sequence call in the :long-description section of the asdf defsystem to fail, unless the default-format is one that can read those characters. It seems that one or more of the following might be appropriate:

1. remove the non-ascii characters

2. set the external-format in the with-open-file form

or 3. Not read the README.markdown file for the long-description. Do we really need all of that loaded into memory?
