I have not used diffall since a few months after the difftool '--dir-diff'
option was released.  Once difftool learned those features, the
diffall script became obsolete.

For people using older git (i.e. before v1.7.11), it may still be useful.
For them, the original out-of-tree repo remains available on github [1].

Pointing to 'difftool --dir-diff' should be enough.

The only change in behavior is that when a working tree file is part
of the diff and is modified during the diff, 'difftool --dir-diff' automatically
keeps the modifications.  The 'diffall' script required the user to use
the '--copy-back' option to do the same.

All other options are exactly the same.

If it would be helpful, I can send a patch that replaces the contents
of 'contrib/diffall' with a README that explains the above and points
to the github repo for people using versions of git prior to v1.7.11.
This would be similar to what was done for 'contrib/vim'.

However, I like the idea of simply removing the directory from contrib
and pointing to 'difftool --dir-diff' in the release notes.
