The existing licence regex assumed each line would start with an unknown
and optional comment delimiter, followed by a required space. However
the standard way to write the licence in XML files uses a multi-line
comment, each individual line simply starts with the licence text, no
delimiter or space. The license check thus needed to be updated to make
the space optional as well.
