0-putty-0.60-original.diff is the original diff.
0-putty-0.60-unchanged.diff is the same diff, but in unified diff format.
x-putty-0.60-everything.diff should have the same functionality, but
strips out all the undesirable whitespace changes that made the
original diff really hard to read.

The other files are the same diff, but sliced up by feature, so that
edits relevant to each feature can be reviewed easily.
