shrink-path: added glob and quote options (#7694) 
* Added -g option to shrink-path plugin.

The new optins adds an asterix to the uniquely shortened name, such
that, if copy'n'pasted, zsh globbing will expand to the full path name
of the shortened path:

shrink-path -g:
"/net/software/modules/modulefiles" -> "/n*/s*/modules/m*"

shrink-path -l -g:
"/net/software/modules/modulefiles" -> "/n*/s*/modules/modulefiles"

* Updated also the README file with the new -g option.

* shrink-path: improved handling of special cases

This commits improves the handling of special cases in path strings:

- handling of white space in path names
- handling of single-letter path names

* Update plugins/shrink-path/README.md

* Fix typo "Asterix" and replace with "asterisk"

* Add optional quoting support to shrink_path

README.md

A plugin to shrink directory paths for brevity and pretty-printing

Examples

For this directory tree:

    /home/
      me/
        f o o/     # The prefix f is ambiguous between "f o o" and "f i g".
          bar/
            quux/
          biz/     # The prefix b is ambiguous between bar and biz.
        f i g/
          baz/

here are the results of calling shrink_path <option> /home/me/foo/bar/quux:

    Option        Result
    <none>        /h/m/f o/ba/q
    -l|--last     /h/m/f o/ba/q
    -s|--short    /h/m/f/b/q
    -t|--tilde    ~/f o/ba/q
    -f|--fish     ~/f/b/quux
    -g|--glob     /h*/m*/f o*/ba*/q*
    -3            /hom/me/f o/bar/quu
    -e '$' -3     /hom$/me/f o$/bar/quu$
    -q            /h/m/f\ o/ba/q
    -g -q         /h*/m*/f\ o*/ba*/q*

Usage

For a fish-style working directory in your command prompt, add the following to
your theme or zshrc:

    setopt prompt_subst
    PS1='%n@%m $(shrink_path -f)>'

The following options are available:

    -f, --fish       fish simulation, equivalent to -l -s -t.
    -g, --glob       Add asterisk to allow globbing of shrunk path (equivalent to -e "*")
    -l, --last       Print the last directory's full name.
    -s, --short      Truncate directory names to the number of characters given by -. Without
                     -s, names are truncated without making them ambiguous.
    -t, --tilde      Substitute ~ for the home directory.
    -T, --nameddirs  Substitute named directories as well.
    -#               Truncate each directly to at least this many characters inclusive of the
                     ellipsis character(s) (defaulting to 1).
    -e SYMBOL        Postfix symbol(s) to indicate that a directory name had been truncated.
    -q, --quote      Quote special characters in the shrunk path

The long options can also be set via zstyle, like

    zstyle :prompt:shrink_path fish yes

Note: Directory names containing two or more consecutive spaces are not yet
supported.
