when a zlib style license gets additional clauses (which, by the nature
of the zlib license, almost certainly restrict the software's usage), it
still gets detected as zlib/png.
the license in question:

i'd like to suggest that licenses with numbered items fail to apply when
followed by a next item, or at least indicate that they have additional
clauses.
(for context: i've found that license in an upstream tarball most of
whose files only contained the three items, and used licensecheck to see
if there are files with different licenses)
