Comment # 8 on bug 903362 from Dr. Werner Fink

Btw: there has been a change between updates

   file /etc/bash_completion.d/calibre.rpmsave is not owned by any package

is caused by such a change.  You may grep for `fc' below
/etc/bash_completion.d/ as well as below /usr/share/bash-completion/ and
/etc/profile.d/*.sh


   grep -rs fc /etc/bash_completion.d/ \
               /usr/share/bash-completion/ \
               /etc/profile.d/*.sh

and also *show* us the results of

   complete -p fc
   compopt -D
