git-rr: show which files were changed in commits, when rebasing

git-rr

#!/bin/sh

# Usage:
# Once you started git rebase --interactive master, and you are presented
# with the list of commit SHAs and commit messages, from Vim:
# - visually select all SHAs via "V}k"
# - launch git-rr: !git-rr
# - ...
# - profit! you now have the same info as before, just with the list of
#   filenames which changed with each commit, and can now move around
#   commits knowing which files were touched by which commit

# Get current branch, without initial "heads/"
BRANCH=$(git describe --all | perl -lne's!^heads/!!;print')

# Kill the "git log" paging features
PAGER=

# Lines look like:
# * c0ffee00 commit message1
# path/to/file1
# <-= newline
# * 00c0ffee commit message2
# path/to/file2
# <-= newline

echo "### START Rebasing branch $BRANCH"
echo "###"
git log --reverse --pretty=format:'* %h   %s' --abbrev-commit --stat --name-only master.. | perl -lne'
    if ( m!^\*! ) {
        s!^\*!pick    !     # by default, show "pick"
    } else {
        s!^!#  !            # just comment-out anything else, with leading spaces for filenames
    }
    s!\s*$!!;               # kill any trailing spaces
    print
'
echo "###"
echo "### END Rebasing branch $BRANCH"
echo "###"

inspired from your script, I did it this way: https://github.com/cfconrad/scripts/blob/master/git/git-rb

It's basically the same, but I do not get the list of commits again, while just parsing the current buffer from stdin...
With this, I don't care about branches --autosqash or rebase.instructionFormat, cause I just don't touch it.
