importers: flymake files break gitinfo
*_flymake.py files are found by the catchall *.py when the importers scan for files relevant to their functionality. As they are not under version control, they produce invalid output from git_info
Possible solutions:
- Modify git_info to ignore them
- Use the .gitignore file as a filter for the files this might be problematic with files added in spite of the ignore file
