zsh completion: disable defaults and verbose output when completing

If ui.verbose is set to True in hgrc, commands used to provide completions
would yield bad results. For example, qpush completion would include the
patch numbers and statuses as returned by qunapplied -v, instead of just
the patch names.

Defaults are also disabled when completing to prevent similar issues when
an option is set that changes a command's output.

hg cat: invalid arguments
hg cat [OPTION]... FILE...

output the current or given revision of files

    Print the specified files as they were at the given revision. If
    no revision is given, the parent of the working directory is used,
    or tip if no revision is checked out.

    Output may be to a file, in which case the name of the file is
    given using a format string. The formatting rules are the same as
    for the export command, with the following additions:

    %s   basename of file being printed
    %d   dirname of file being printed, or '.' if in repository root
    %p   root-relative path name of file being printed

options:

 -o --output   print output to file with formatted name
 -r --rev      print the given revision
    --decode   apply any matching decode filter
 -I --include  include names matching the given patterns
 -X --exclude  exclude names matching the given patterns

use "hg -v help cat" to show global options
