The only explanation I can imagine is that the parser doesn't
see the % because in fact it is *inside* a quoted string. For
example, if you accidentally put a quote-mark at the end of a
line somewhere earlier in the code, like this:

#(set-global-staff-size 16)"

%\include "04_fig.ly"


the parser will actually see this:

1. scheme command: #(set-global-staff-size 16)
2. quoted string: "

%\include "
3. unsigned integer: 04

Here it will stop parsing because it doesn't have any 
instructions on what to do if it reads a number in that context.
Perhaps the problem could be in one of the included files? I
don't know enough to say for sure if that's something that could
happen. Use

%{
   multi-line comments
%}

to isolate potential culprits...

I would recommend that you format your file to fit (uncompromisingly)
within at most 72 lines, to prevent certain problems. For example, I
copied your code directly into a file, which compiled with errors
because the curly braces were not matched. Here is the structure:

\book {
  \header {
    title = { ... }
    subtitle = { ... }
    subsubtitle =  { ... }
    %composer = { ... }
    copyright =  ...
%   tagline =  { \concat {
       ...}
    }

I assume you meant to comment out all of the tagline? Perhaps it was 
originally on one line in your file, but perhaps through e-mail it 
gained one or two line-endings. Which means that

     ...}
  }

is not commented out. Multi-line comments are done like this:
%{
   tagline =  { \concat {
       ...}
    }
%}

But by doing this, it becomes clear that the \header and \book braces
are not closed. So here's a clearer indentation:

\header {
  title =  {    
    <long>
  }
  subtitle = {
    <long>
  }
  subsubtitle = <short>
  composer = <short>
  copyright = <short>
  tagline =  {
    <long>
  }
}

Note that curly braces can safely be removed if there is only one
item:

subsubtitle = \markup \smallCaps "string"

So here's your file re-formatted with some changes:

1. title: \center-align --> \center-column
   (I assume that's what you meant)
2. subtitle: used \pad-to-box to balance the vertical spacing
3. subtitle: used \concat to break 1 string into 2 lines of code.
4. subsubtitle: removed unnecessary curly braces.
5. composer: removed \markup \center-column since it does nothing.
6. tagline: removed \roman (default is roman already)
7. tagline: #(x11-color "red") --> #red
8. tagline: removed \with-color #(x11-color "black") since the
   color reverts back to black automatically anyway.

HTH.
