String::Ediff will be used by CVSweb if it's found; if not, the internal
colorization of CVSweb will be used in "human readable diffs" so you
don't need to install any additional modules.  String::Ediff provides
enhanced diffs in the sense that it pinpoints the actual changes instead
of marking whole rows changed, but as said, it has some issues with
whitespace.

If you don't like that behaviour, either remove the String::Ediff module
or change the line (around line number 112) in cvsweb.cgi from:

  use constant HAS_EDIFF    => eval { require String::Ediff;  };

...to:

  use constant HAS_EDIFF    => 0;

Hm, perhaps the choice to use String::Ediff or not (if it's available)
should be made configurable in the UI on per-user basis.  I've added
that to the TODO list.
