How to preserve indentation of title inside a latex src block when exporting to LaTeX?

[Edgar Lux <edgarlux@mailfence.com>]

Hello. How to preserve indentation of title inside a latex src block when exporting to LaTeX?

For (annoying) reasons, I need a frontmatter block which is able to indent its contents. I am almost there, but the title line is not. I can edit this manually after export, but I would like to know if there is a way to do this... wait... there are filters. Is a filter the only solution? Thanks. 

#+options: toc:nil title:nil timestamp:nil

#+begin_src emacs-lisp
  (org-babel-do-load-languages 
     'org-babel-load-languages 
     '( (latex       . t) ))
#+end_src

#+begin_frontmatter
  #+begin_src latex -i :exports results :eval yes :results replace
  \title{Determine in-situ matrix properties}
  \nothing{a}
  #+end_src
#+end_frontmatter

#+caption: Notice that title is not indented, but nothing is.
#+results:
: \begin{frontmatter}
: \title{Determine in-situ matrix properties}
:  \nothing{a}
: \end{frontmatter}

#+begin_src emacs-lisp
  (concat (emacs-version) "\n" (org-version))
#+end_src
