Subject: Fix a few completion problems

  1. Bug 7674: adjust shopt such that nullglob won't change non-comps that have special formatting.
  2. Fix problem with default completion not working properly when using the same string i.e. 'sh sh'
     for 'show shutdown' couldn't complete 'shutdown' until 'sh shu' was typed.
