Comment 1 for bug 1483468

Tried forcing the SOURCES.txt to be re-created so that new file will be included, however pbr does not include all the source code because it relies on checking if files are tracked by git to be included in the SOURCES.txt

An option would be for patch files adding new files:
1. add support for apply patches using "git am "

2.. Use a .git.patch option and move those patch file into the "download" directory so that the new files will be available before sdist is invoked.
