Sorry for this ``blank'' patch, but Vcs removes any white space in altered
lines in diffs.
BTW, is there an option to disable this behavior in Vcs? If not, I
suggest adding an option like `--show-space-change' (i.e., the
opposite from diff's --ignore-space-change).
Here is a more readable diff:
LOL.

What's the problem with icpc? Why does it actually *need* whitespaces there?

The choice of displaying whitespace changes or not must be left to
the user, even if there's a default behavior (not to show them, in the
current case).
And the problem is even bigger: think of Python files, where
indentation matters. For this case, Vcs or svn-wrapper could use
libmagic (i.e., `file') to check the type of the file(s), and adjust
its behavior.
P.S.: BTW, I suspect `file -i' of being buggy on Debian:
brasilia ~ % file ~/src/tc/dev/ast-nodes-gen 19:12 #210
/home/levill_r/src/tc/dev/ast-nodes-gen: a python script text executable
brasilia ~ % file -i ~/src/tc/dev/ast-nodes-gen 19:12 #211
/home/levill_r/src/tc/dev/ast-nodes-gen: text/x-java; charset=us-ascii
:)
(Micha just said to me he observed a similar behavior on Gentoo...)
