I disagree.  When every paragraph is in fact just one line, the VCS
diffs are usually huge and it's extremely hard to spot the actual
modification.

Yes, when writing docs together with people with inferior editors, I
also use visual-line-mode.

If you already use Emacs 24 with it's integrated package manager,
there's the adaptive-wrap package on GNU ELPA.  That visually indents
the wrapped around lines according to the indentation of the previous
line.  So your example above would be shown as

\begin{definition}
  Bla bla bla bla bla bla bla bla
  bla bla bla bla bla bla bla bla
  bla bla bla bla
\end{definition}

where all the bla-blas are actually on one logical line.

I activate this mode whenever visual-line-mode is enabled:

  (add-hook 'visual-line-mode-hook 'adaptive-wrap-prefix-mode)
