The 'lvconvert LV' command def has caused multiple problems for command matching because it matches the required options of any lvconvert command. Any lvconvert with incorrect options ends up matching 'lvconvert LV', which then produces an error about incorrect options being used for 'lvconvert LV'. This prevents suggestions from nearest-command partial command matches. Add a special case for 'lvconvert LV' so that it won't be used as a partial match for a command that has options specified.
