Make license texts YAML safe

License texts were producing invalid YAML files when there were
different indentations in the text along with empty newlines, and
to make these texts YAML safe we add a single space to empty
newlines to license texts with different indentation levels.

                 Preamble
-
+ 
 The intent of this document is to state the conditions under which a
 Package may be copied, such that the Copyright Holder maintains some
 semblance of artistic control over the development of the package,
 while giving the users of the package the right to use and distribute
 the Package in a more-or-less customary fashion, plus the right to make
 reasonable modifications.
-

 Definitions:
-
+ 
     "Package" refers to the collection of files distributed by the
     Copyright Holder, and derivatives of that collection of files
     created through textual modification.
-
+ 
     "Standard Version" refers to such a Package if it has not been
     modified, or has been modified in accordance with the wishes
     of the Copyright Holder as specified below.

+ 
     "Copyright Holder" is whoever is named in the copyright or
     copyrights for the package.

     "You" is you, if you're thinking about copying or distributing
     this Package.
-
+ 
     "Distribution fee" is a fee you charge for providing a copy

-
+ 
     "Freely Available" means that no fee is charged for the right to
         use the item, though there may be fees involved in handling the
         item.  It also means that recipients of the item may redistribute
         it under the same conditions they received it.

 1. You may make and give away verbatim copies of the source form of the
 Standard Version of this Package without restriction, provided that you
 duplicate all of the original copyright notices and associated disclaimers.

 derived from the Public Domain, or those made Freely Available, or from

 that you insert a prominent notice in each changed file stating how and
 when you changed that file, and provided that you do at least ONE of the

     Freely Available, such as by posting said modifications to Usenet or an
     equivalent medium, or placing the modifications on a major network
     archive site allowing unrestricted access to them, or by allowing the
     Copyright Holder to include your modifications in the Standard Version
     of the Package.
-
+ 
     b) use the modified Package only within your corporation or organization.
-
+ 
     c) rename any non-standard executables so the names do not conflict
     with standard executables, which must also be provided, and provide
     a separate manual page for each non-standard executable that clearly
     documents how it differs from the Standard Version.
-
+ 
     d) make other distribution arrangements with the Copyright Holder.

        permission to make your modifications Freely Available
        in some specific way.

 4. You may distribute the programs of this Package in object code or
 executable form, provided that you do at least ONE of the following:
