How about this instead:

search_reflog () {
	sed -n 's/\([^ ]*\) .*\tcheckout: moving from $branch .*/\1/p' \
		< .git/logs/HEAD
}

Of course, this leaves out the merges... but I'd make that a command line option anyway: would you like to resurrect a branch that you recently were on, or one that you recently merged, or one that was merged by someone else?
