Superfluous spaces in `match` of some GFDL-1.x-* standard header templates

[snazy]

The following GFDL license standard header templates contain a var/match with rather superfluous spaces in the regex:

• GFDL-1.1-invariants-only
• GFDL-1.1-invariants-or-later
• GFDL-1.1-only
• GFDL-1.1-or-later
• GFDL-1.2-invariants-only
• GFDL-1.2-invariants-or-later
• GFDL-1.2-only
• GFDL-1.2-or-later
• GFDL-1.3-invariants-only
• GFDL-1.3-invariants-or-later
• GFDL-1.3-only
• GFDL-1.3-or-later
  The other GFDL license details (e.g. GFDL-1.3) are fine.

For example, the GFDL-1.3-only standard header template (line wraps for posterity by me) looks like this:

Copyright (c) 
<<var;name=\"copyright\";original=\"YEAR YOUR NAME\";match=\".+\">> 
 Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3; with
<<var;name=\"invariantSections\";original=\"the Invariant Sections being LIST THEIR TITLES\";match=\"the Invariant Sections       being .+|no Invariant Sections\">> 
 , with
<<var;name=\"frontCoverTexts\";original=\"the Front-Cover Texts being LIST\";match=\"the Front-Cover Texts being .+|no Front-Cover Texts\">> 
 , and with
<<var;name=\"backCoverTexts\";original=\"the Back-Cover Texts being LIST\";match=\"the Back-Cover Texts being .+|no Back-Cover Texts\">> 
 . A copy of the license is included in the section entitled \"GNU Free Documentation License\".

The 2nd var has the match with the pattern the Invariant Sections being .+|no Invariant Sections (notice the many spaces), which doesn't match the corresponding part of standard header template text ("the Invariant Sections being LIST THEIR TITLES"), which has only one space.
