Quick note on the license title 'BSD-tiff-ish'

The original tif_lzw.c from the libtiff distribution contains two licenses
information, one at the top of the file, one at the bottom of the file.
Therefore it cannot be under the BSD tag for the debian distribution. For the
same reason it cannot be under the 'BSD and BSD' tag (dep5 notation).
This 'BSD-tiff-ish' tag name is meant to be unique in this case for tiff.

The first license looks like a BSD-4 license. The second one looks like the
original BSD license
