relocatable-shell: Update suggested usage in maintainer documentation. Instead of suggesting an inline usage of "sed", that would have to be cut-and-pasted for every directory to be relocated, suggest a shell function. Make the example obviously an example, whereas previously it looked like it might be literal text. Thanks to Reuben Thomas <rrt@sc3d.org> for pointing out these issues. See http://lists.gnu.org/archive/html/bug-gnulib/2014-01/msg00039.html for further context.

 You must adapt the definition of @code{orig_installdir}, depending on
 where the script gets installed.  Also, at the end, instead of
-@code{gettext_dir}, transform those variables that you need.
