--stat added, jumpstat alias removed.

Options passed to the `j` function will now be passed on autojump. As a result,
directories beginning with `-` are no longer supported.

A -s short alias for --stat is added. Instead of using jumpstat, use `j --stat`
or `j -s` instead.

As best I can tell, ZSH introduced the "=~" condition somewhere around 4.3.5 or
4.3.9. In either case, autojump will use =~ for versions higher than 4.3.5 and
  -pcre-match for older versions of ZSH.

In the past the installer would modify the user's ~/.bashrc and thus needed to
find the current user's name and home directory. However, the installer no
longer modifies user's ~/.bashrc and getent also outputs error messages for
Cygwin users.

Use -pcre-match in .zsh instead of =~.

Before zsh 4.3.5 =~ was not supported. This results in the message
'autojump.zsh:18: condition expected: =~'.

Not sure if this is correct, is there a source file I should update
instead?

Defining argument strings explicitly as unicode causes problems in Python v3,
and the arguments are tested anyway in encode and decode functions.

Documentation and install scripts now instruct older Python users to upgrade
their Python version or install older versions of autojump.

'install.sh' now gets a -f|--force option, which makes the install ignore
Python dependency requirements.

This was caused by the rewrite to use argparse over optparse to handle command
line arguments.
