Re: A better git diff --word-diff (--word-diff-regex) ?

is there a way to configure --word-diff to be a more programming
language friendly? For example if I add one parameter to a function
declaration, I'd like to see only the addition of the parameter as the
change. But currently it shows much more.

For example if
  void foo(int x);
is changed to
  void foo(int x, int y);
I'd like to see only ",int y" as the change, not "x, int y);".

I think I'd like to ignore all white spaces and tokenize text on word
boundaries and see the diff between the tokens. This way if I e.g. add
a missing ";" it'll be shown as the only change.

Umm, what's wrong with

  echo '*.cpp diff=cpp' >>.git/info/attributes

Ok, the funcname patterns aren't so good, but the word regex is designed
to "tokenize" as far as that is feasible.

Thanks, that's very good! I've missed it reading the git-diff man page.
