certain mlint errors aren't displayed by flycheck

[dsharoh]

First off, thanks for your work on matlab-mode!

It seems that errors with a range of column extents, those with a dash, are not highlighted in matlab buffers with flycheck-mode enabled.
For example a nasty error like this:
<< L 19 (C 9-11): INV(A)_b can be slower and less accurate than A\b. Consider using A\b for INV(A)_b or b/A for b*INV(A). >>

Would not be highlighted in the matlab buffer seemingly due to the << (C 9-11) >> portion.

Errors like this:
<< L 7 (C 6): Terminate statement with semicolon to suppress output (within a script). >>

Would be highlighted as expected.

I was able to fix this problem with this modification to my flycheck-matlab-mlint.el
From line 63:

;; old line
;'((warning line-start "L " line " (C " (1+ digit) "): " (message) line-end))
;; new line
'((warning line-start "L " line (message) line-end))

I don't know if this is a good solution or if there is a better one, but I am at least seeing my errors now.
