- _command(): commands like 'sudo chown' return completions of the form

Browse Source 
'user:'. This gets escaped by _chown() and passed back as 'user\:'.
  _command() then escapes this further to 'user\\\:', so we need to unescape it
  to have things work correctly.

  Unfortunately, 'sudo rm' might pass back the name of a file that has a
  backslash followed by a colon in the name, e.g. 'foo\:bar'. This is
  escaped by _command() to 'foo\\\:bar', which we should not unescape.

  How to tell the difference between a completion that contains a backslash
  that is escaping the following character, and one that has literal
  backslashes?

  We extract the '-o <type>' information from the compspec and, if we are
  dealing with a spec that does not specify that it passes back filenames or
  dirnames, we unescape any backslash/colon pairings. Of course, this means
  that 'sudo chown' will still do the wrong thing when dealing with a
  directory or filename that contains '\:'. Oh well...
