Single row CSV: last value not parsed

[elehcim]

Hi,
I just happened to find a weird behaviour of readcsv. Having a very long single line (1 row) file of comma separated values, I used the function readcsv() to import it but the last value was not imported. Adding a carriage return or another comma at the end of the line makes readcsv behaving correctly.

Examples:

file:

2,3,4,2

julia> w=open("1.csv"); e=readcsv(w); close(w); e
1x3 Array{Float64,2}:
 2.0  3.0  4.0

(where's the last "2"?)

---

file: (carriage return at the end of the line)

2,3,4,2

julia> w=open("1.csv"); e=readcsv(w); close(w); e
1x4 Array{Float64,2}:
 2.0  3.0  4.0  2.0

---

file: (comma at the end)

2,3,4,2,

julia> w=open("1.csv"); e=readcsv(w); close(w); e
1x4 Array{Float64,2}:
 2.0  3.0  4.0  2.0

This happens also with string values but it doesn't happen when the file has multiple rows.

Seems to be working fine on my setup.
Shall update to latest master and confirm.

Note that tools like nano will automatically put a newline at the end of your file. Try the following to generate data that exhibits the problem:

$ echo -n "2,3,4,2" > test.csv
$ julia -e 'show(readcsv("test.csv")) && echo
1x3 Array{Float64,2}:
 2.0  3.0  4.0
$

I put the && echo there just so that we'd get a newline at the end of the output. This is on:

Found the bug. Was there in my earlier setup as well. Shall push a fix shortly.
