I have implemented it for 'diff'. With this, I no longer need to have
an external diff configured for ignoring eol changes. I am sending a
patch on current crew tip. I am not sure if it is a better idea to
have a 'diff' extension. Since it touches the core of and VCS system,
I am not sure where it belongs. 'diff' is also something that users
may want to extend.
For example:
 1. The is a tool that generates log files with a date stamp in the header
2. The execution of tool at various times will (or may) generate the
same logs with different timestamps.
3. I would like to extend diff to strip those time stamps so that
logically there is no difference in the contents (as I intentionally
want to ignore the timestamp)

Well, I could use an external diff but if I could just massage the
input for the internal diff, I will be able to realize my requirement.
The above scenario happens more in real life when I handle files in
CVS through hg (and CVS). The CVS specific fields like author, rev,
date gets modified on each new checkout. I would like to ignore those
fields.
