Warn cloners if there is no LICENSE* or COPYING* file that makes
the license clear. This is a useful warning, because if there is
no license somewhere, then local copyright laws (which forbid many uses)
and terms of service apply - and the cloner may not be expecting that.
Many projects accidentally omit a license, so this is common enough to note.
