With this script, and a git alias:

	git config --global alias.klog '!sh -c '"'"'last=""; next_to_last=""; args=""; for arg in "$@"; do [ -n "$next_to_last" ] && args="$args $next_to_last"; next_to_last="$last"; last="$arg"; done; hash=$(git-disambiguate.sh "$next_to_last" "$last") && git log $args "$hash"'"'"' -'

We can have (git-log compatible) git-klog find the right commit for us:

	$ git klog --oneline -1 cff8 '("net: phy: avoid ... *_led_polarity_set()")'
	cff865c70071 net: phy: avoid undefined behavior in *_led_polarity_set()

Which means that folks should be able to use a fairly short abbreviated
commit IDs in messages, specially for commits with a long subject line.
