Details:


Some csv files generated by some other software, contained a "\0" before the
end of file. When trying to read this file, an extra row with zeros has been
added to the resulting matrix. 

The attached patch shows the problem in the test/assert statement, and
provides a solution. 

Other solutions than "if(!strlen(line.c_str()))" did not seem to be
successful. line.length() is 1, and line.empty() was zero. when the line "\0"
was read.
