 I meant to include another example closer to home, so to speak, as a
 specific test case others could try duplicating.  (That might sound
 kind of redundant, given what the problem appears to be, but just to
 demonstrate it doesn't seem specific to some interaction with a
 particular server, I can duplicate the problem with NetBSD's ftp site
 too.)
 
 Here's an mget I did in /pub/pkgsrc/distfiles:
