>Description:

The cp(1) command produces surprising behavior when copying multiple
files to a destinationd directory.  The files are copied in reverse
order.  This is of consequence when the order of files in a directory
has meaning; e.g., in an mp3 player appliance the sequentially plays
files in an MS-DOS filesystem directory.

This is very counter-intuitive to the user.

>How-To-Repeat:
 mkdir /tmp/foo /tmp/bar
 touch /tmp/foo/1 /tmp/foo/2 /tmp/foo/3 /tmp/foo/4 /tmp/foo/5 /tmp/foo/6
 cp -v /tmp/foo/1 /tmp/foo/2 /tmp/foo/3 /tmp/foo/4 /tmp/foo/5 /tmp/foo/6 /tmp/bar

>Fix:

BTFOM.  Sneaking suspicion that mastercmp() and related callers are
implicated in this.
