Hello Greg,

Thank you for your reply. You are somehow right. Here is what I get
after "complete -r":

   * After "complete -r" when only the default bash completion is
     used the completion works well.

   * Without 'complete -r', when programable completions are used, after
     "shopt -s nullglob" completions do not work at all.

When I run the command 'complete' I see many compspecs defined on
my machine (Debian GNU/Linux 8.10 (jessie)). I am not able to
figure out which one of these compspecs causes this behavior.
If this is not a behavioral bug, then it I think that it can be considered
a documentation bug the fact that 'shopt -s nullglob' can alter
is not specified in the manual.

Cristian
