Improves resolving of file names from git diff files when paths contain whitespace.
Does not entirely solve the issue as it might incorrectly present file name with " b/" in path e.g.
diff --git a/repo/dir b/file.txt b/repo/dir b/file.txt
but still even in that case the output will be much better as previous "split()" just lost part of the information
current:
- origFile = repo/dir 
- newFile = file.txt
after fix:
- origFile = repo/dir
- newFile = file.txt b/repo/dir b/file.txt

I dont think having " b/" in path is an often case :)

Further improvement could be to read the file names from +++ and --- lines in diff_line contains more than one occurrence of " b/"
