Hi Stefan, thanks for the response.
Being able to set `diff-command' to any external program is a great
feature in Emacs, in my experience. I have been using it for many Emacs
versions, and I would miss this capability if it would be removed from
Emacs 24.
In Windows I set `diff-command' to "winmerge" and in Linux I set it to
"kompare". Next week I might set it to whatever I find the most efficient
diff program for me.
This lets me view the differences in a feature-rich external diff program.
I can visualize the differences between my modified buffer and saved state
much more efficiently than with diff. Sure, diff is okay for visualizing
the changes, ediff would be better, but really the external diff programs
are much more efficient for me. My `ediff-mode-hook' is extensive, but I
still find the external programs more efficient.
I understand that pure diff is, well, pure. But I remember how impressed
and thankful I was when I disovered the flexibility of `diff-command', and
I'm guessing many other Emacs users have found it practical to set it to
something other than "diff". Comparing changes is an important task when
editing, and it's great that Emacs can delegate this task to specialized
programs, although the default is to handle things within Emacs.
Best regards,
Arni
