1) Is there a way to check whether there are white spaces in this
file without running git-apply?
"sed -n -e '/^+.*[ ]$/p' patch.txt" perhaps?
2) Is there a way to get some messages about that there are white spaces
when creating a git patch?
Doesn't "git diff" highlight whitespace errors? That way, you can catch
errors before you make a commit that has them.
