Details:

I am using octave 3.8.0-6 OS X mavericks dmg downloaded from

http://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/2013-12-30%20binary%20installer%20of%20Octave%203.8.0%20for%20OSX%2010.9.1%20%28beta%29/


I tried to import a plain text file (attached landmarks_list.txt) which looks
like:

Landmark-1
Landmark-2
Landmark-3
Landmark-4
Landmark-5


i.e it has no headers and a single column.

Loading this file using any of the following 

A=importdata("landmarks_list.txt")
A=importdata("landmarks_list.txt","t")
A=importdata("landmarks_list.txt","t",0)
A=importdata("landmarks_list.txt"," ")
A=importdata("landmarks_list.txt"," ",0)

all fail with:

error: importdata: Unable to determine delimiter
error: called from:
error:   /usr/local/octave/3.8.0/share/octave/3.8.0/m/io/importdata.m at line
214, column 5
error:   /usr/local/octave/3.8.0/share/octave/3.8.0/m/io/importdata.m at line
132, column 38

I then tried an older version of importdata.m taken from
http://sourceforge.net/p/octave/feature-requests/41/
and it worked like a charm.
There seems to be some issue with the delimiter detection.

NOTE: There is not path/file not found issue

NOTE: I have tried this with multicolumn files with a valid "t" delimiter and
this fails too with the latest importdata and it passes with the older
version.
