Why does the CSVREAD function not read in my data in MATLAB?

The following data file is not read correctly by the CSVREAD function:
1, 2, 3, 4
5, 6
When I use CSVREAD to read in this data file, I receive the following output:
Warning: Input arguments must be scalar.
> In dlmread>cell2array at 204
In dlmread at 145
In csvread at 45
??? Error using ==> vertcat
All rows in the bracketed expression must have the same
number of columns.
However, if I press Enter after the '6' in the text file, the file is read in with no problem and returns the expected data:
ans =
1 2 3 4
5 6 0 0
Why does this happen?

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:
This is a bug in the way CSVREAD handles text without the same number of elements in each row when there is no terminating carriage return. To work around the problem, insert the carriage return at the end of the data file.
