So far, I've been unable to reproduce that on Fedora 16 or Debian unstable
both x86_64.  I.e., the following (equivalent to above, but with no long
lines) always prints the four input lines:

cert=libcore/luni/src/main/java/java/security/cert
echo \
 $cert/X509CRLSelector.java \
 $cert/X509CertSelector.java \
 $cert/X509Certificate.java \
 libcore/luni/src/main/java/javax/security/cert/X509Certificate.java \
 |tr ' ' '\n' |sort -u --debug
