	Is -name x\* less legible than | grep '/x[^/]*$'?

	The issue of the code readability is the consequence of using
	the tools not quite designed for the task.  And sort(1) is not
	designed to search for N rows having minimum (or maximum) keys.
	(ISTR that there was such a tool.)

	I've seen file archives with 300 000 files and more.  There,
	sorting doesn't seem like a proper choice, unless it's a
	throw-away code for a one-time task.
