Details:

in the current version of importdata.m the header lines can appear duplicated
in the output.textdata section if the wrong number of header lines is
suggested by the user

I have created a patch that solves the issue, moreover I have also added a
warning to the user when the auto-detected number of headelines is greater
than the value asked by the user (in that way the user doesn't get many NA
lines at the beginning of output.data)

I have added here a test datafile to show the problem:


importdata('test.log',"\t") % no problem here
importdata('test.log',"\t",1) % problem is here evident
