Previously, attributes consisting of a single nominal value whose name is 1 character will cause "loadarff" to fail (admittedly, this is a bit of an edge case).
Adds a test case covering this issue.
Adds failing test for nominal arff reading
The arff io reader fails to load arff files containing
a single nominal value of only 1 character. Adds a
test demonstrating the failure in this case.
Fixes failing test of arff reader
Alteres the regex for parsing nominal values in
arff files so that single character nominal
values can now be successfully parsed.
Fixes arff io test name
Coverage remained the same when pulling e6fceed on ghl3:arff_nominal_fix into 11d8bee on scipy:master.
Thanks George, looks good to me.
