Neuroscan file close bug (Was: Data concatination)

Okay, just to follow up on my own message: The skeleton code below, led
to a "Too many files open" error after preprocessing four subjects,
causing any I/O functions of MATLAB to freeze:
After some debugging, I found that in the file
private/read_neuroscan_cnt.m the read function returns when headeronly
is given as an argument, without closing the filehandle first.
Attached is a fix.
