Subject: Fix a few completion bugs

1. Bugfix 8254: Show the help text first so users don't think there is
only one completion for a value when it exists with non-comps
2. Fix config mode inconsistencies with operational mode. Show all
values in help text.
3. Fix "exists_only" command handling. Only show nodes that exist when
doing completion for show, comment, and delete.
