jj git-index diff editor (v2)

	# This diff editor uses the state of the git index (staged files) to edit the diff.
	# This gives an effect similar to `git commit`, which can be useful due to tooling
	# often being high-quality for using the git index to split up changes.
	#
	# This tool is designed to be used with the commit, split, and squash commands.
	# This is made easier with some aliases. A custom merge-editor definition is unneeded.
	#
	# LIMITATIONS:
	# 1. jj doesn't allow a diff editor to edit files which are only changed in the index,
	# and unchanged in the working copy, those will be discarded.

	# and sums the maximum job counts for all x86-64 machines.
	# It can be used in your mozconfig as follows:
	# mk_add_options MOZ_MAKE_FLAGS="-j$(icecc-jobs)"
	# if this script is on your PATH, and named icecc-jobs
