>Description:
When printing the message error, the realpath(1) utility uses the buf passed to
realpath(3) instead of the passed argv[1].  When errno is set to ENAMETOOLONG, it
prints the current directory, which is misleading, IMO.
>How-To-Repeat:
$ cd /
$ realpath `perl -e 'print "A"x1026'`
realpath: /: File name too long
$ cd /tmp
$ realpath `perl -e 'print "A"x1026'`
realpath: /tmp: File name too long
