Dialect weirdness

[joshribakoff]

I created a file with this php code/string:

$csv = "sku,name\n";
$csv.= "123,name";

Then I open it with the reader:

new Csv_Reader($path);

I get, "Csv_Exception_CannotDetermineDialect: You must provide at least ten lines in your sample data".

Simply passing a Csv_Dialiect with no custom options bypasses that error and imports my CSV data fine:

new Csv_Reader($path,new Csv_Dialect);

The "auto dialect" feature should be smart enough to handle this without an exception!
