test_new.diff had some issues which would cause
errors if trying to actually use the diff file
with 'patch' to create the files it references.
1) had some line numbers which were invalid
2) had path specifications and, unfortunately,
'patch' does not support creating absent directories
The file has been cleaned up to have the create
line numbers and to assume that all files are at
the root.
Additionally, for the few cases where the diff
file referred to an edit rather than creation of a
whole new file, those diff hunks were moved into a
new, separate, file.
There is no functional change with this commit,
but it sets up future test features.
