[O] Small fix for Org manual

[Vladimir Lomov]

Hello,
recent changes in org-manual.org (commit
b94e6e2b459d03429f983b2b11ed6a3095b9d12c) breaks typesetting from texi
to pdf (texi2pdf). I made small fix for the issue.

When you are in the middle of a story it isn't a story at all, but
only a confusion; a dark roaring, a blindness, a wreckage of shattered
glass and splintered wood, like a house in a whirlwind, or else a boat
crushed by the icebergs or swept over the rapids, and all aboard
powerless to stop it.  It's only afterwards that it becomes anything
like a story at all.  When you are telling it, to yourself or to
someone else.
