+# Stage all diffs found in currently staged files
+
+# This is useful if you've got a set of files ready to commit, but edited one
+# or more of them (via prettier, delinting, deleting debug statements, adding
+# more tests, ...), and want to make sure those changes are included.
+
+# Usage: `git restage`
+
+# Installation: add this script to your $PATH and chmod +x.
+
+# Hop down to the root of the repository so paths are correct:
+cd "$(git rev-parse --show-toplevel)" || exit 1
+
+# For all currently staged files, call `git stage`:
+git diff --name-only --cached | xargs --verbose -n 1 -- git stage
