bug in ls -1U: argument files printed after their contents

[Julian Bradfield]

This hit me with the RH EL5 package coreutils-5.97-19.el5 .
I also see it in a build from clean coreutils-7.4 GNU release.

Problem: when printing files with the -1U options, and more than one
file is given on the command line, the argument files are printed
after their contents instead of before.

Transcript demonstrating bug:
-------------------------------------------
krk: mkdir /tmp/LSBUG
krk: mkdir /tmp/LSBUG/a
krk: mkdir /tmp/LSBUG/b
krk: touch /tmp/LSBUG/a/1
krk: /bin/ls -1U /tmp/LSBUG/a /tmp/LSBUG/b
1
/tmp/LSBUG/a:

/tmp/LSBUG/b:
krk: 
-------------------------------------------

Of course, this breaks any script that relies on that format, as well
as baffling human users. Since this bug doesn't seem to have been
reported yet, I guess I must be the only person left on the planet
running a 15-year old Cnews suite, where the expire script relies on
it and completely breaks.

Since I see it in RH 5.97-19, which includes the "lsmemoryexhausted"
patch:

and I don't see in GNU 6.12, which doesn't include that patch, and I
do see it in GNU 7.4, which does, and the patch is obviously relevant,
I blame that patch.

I don't have a fix.
