Bug#184074: readlink behavior different from debianutils version.

[Junichi Uekawa <dancer@netfort.gr.jp>]

Package: coreutils
Version: 4.5.9-1

debianutils "readlink -f" allowed non-existing files to be 
completed. But coreutils readlink does not have the same behavior.

pbuilder was affected, and I think other packages may be affected too.

readlink in debianutils used to have this documentation:
     -f    Using realpath(3), canonicalize by following every symlink in every
           component of the given path recursively.  Note that the resultant
           pathname might not exist,




sid$ readlink -f random-name ; echo $?
1


woody$ readlink -f random-name ; echo $?
/home/dancer/random-name
0
