File renames aren't handled properly because PatchSet.path returns a source filename

[ghost]

File renames aren't handled properly because PatchedFile.path returns a source filename which doesn't exist after the operation. Probably it should return a target filename.

python-unidiff/unidiff/patch.py

Line 369 in 9a473c8

filepath = self.source_file

Due to that, tools which detect changed files (like lint-diffs) use non-existing files.

from unidiff import PatchSet
diff_str = """Submodule sub bc856b3..d7ac133:
diff --git a/sub/file.txt b/sub/renamed.txt
similarity index 100%
rename from file.txt
rename to renamed.txt"""
patch = PatchSet.from_string(diff_str)[0]
print(patch.source_file)
print(patch.target_file)

Returns:

a/file.txt
b/renamed.txt

I would expect "sub/" to be part of the source and target file.

I see, returning target file for renamed files makes sense.
OTOH, thanks for the additional report and the example, you are right, it should include the sub/ in the path.

Will take a look.
