zsh 3.1.9-dev-6: trace output filename problem with patch

["E. Jay Berkenbilt" <ejb@xxxxxx>]

When inserting the command to look at the trace output from ^X? in an
editor, zsh forgets to quote the filename.

  zsh% \ls^X?
  Trace output left in /tmp/zsh1708\ls1 (up-history to view)
  ...

  ^P

  emacsclient /tmp/zsh1708\ls1 ;: '\ls'

The problem: the \ in the filename needs to be quoted here but isn't.

The same things happens if there are other characters that require
quoting (such as *) in the first word.  When inserting the editor
command into the history in _complete_debug, can't zsh quote $tmp?
Here is my suggested fix, made from the installed
3.1.9-dev-6/functions directory:
