    _______________________________________________________

Details:

the following code causes a "error: strncmp: N must be greater than 0"
error.

lines = { '', '% comment line', 'var a = 5', ''}
strmatch ('', lines, 'exact')


Octave 3.2.4 and Matlab correctly return [1;4] as the answer.

even though it's not related to the fix: Matlab does allow 0 and negative
length values for n within strncmp (it simply returns true for any two
arguments).
