fix to allow spaces in file name/path

[Jidehem]

If you have spaces in file names or in path, the current implementation will fail because of awk '$1 == "D" { print $2; }' that will extract only the first part of the file path, up to the first space.
The fixes implements a way to circumvent this using sed

I noticed that the change introduces CR LF newlines.
It can be fixed directly with:

git commit --amend --no-edit -a
