[git] How to show changed file name only with git log?

Now I use the following to get the list of changed files my current branch has, comparing it to master (the compare-to branch is easily changed):

git log --oneline --pretty="format:" --name-only master.. | awk 'NF' | sort -u

Before, I used to rely on this:

git log --name-status <branch>..<branch> | grep -E '^[A-Z]\b' | sort -k 2,2 -u

which outputs a list of files only and their state (added, modified, deleted):

A   foo/bar/xyz/foo.txt
M   foo/bor/bar.txt
...

The -k2,2 option for sort, makes it sort by file path instead of the type of change (A, M, D,).
