issues: simplify example in ini file

The example setting from the default ini file is:
issue_pat = (?:\s*#)(\d+)
issue_server_link = https://issues.example.com/{repo}/issue/{id}
issue_prefix = #

in which the clause '(?:\s*#)' is overly complex:
1. '\s*' means optional whitespace, which means there can be whitespace or
no whitespace, which means that you could equally write:
(?:#)(\d+)
(If any leading whitespace was eaten by the regexp, 32e1e0745d3c would take
care to restore a part of it.)
2. '(?:xxx)' means a non-capturing set of parentheses. In this case this is
equal to just mentioning 'xxx'. So the simplified pattern becomes:
#(\d+)

If instead of _optional_ whitespace, _mandatory_ whitespace was intended,
then the pattern should be different. But this would also mean that
patterns like PR#123 would not be matched anymore.

===============
Troubleshooting
===============

:Q: **Missing static files?**
:A: Make sure either to set the ``static_files = true`` in the .ini file or
   double check the root path for your http setup. It should point to
   for example:
   ``/home/my-virtual-python/lib/python2.7/site-packages/kallithea/public``

|

:Q: **Can't install celery/rabbitmq?**
:A: Don't worry. Kallithea works without them, too. No extra setup is required.
    Try out the great Celery docs for further help.

|

:Q: **Long lasting push timeouts?**
:A: Make sure you set a longer timeout in your proxy/fcgi settings. Timeouts
    are caused by the http server and not Kallithea.

|

:Q: **Large pushes timeouts?**
:A: Make sure you set a proper ``max_body_size`` for the http server. Very often
    Apache, Nginx, or other http servers kill the connection due to to large
    body.

|

:Q: **Apache doesn't pass basicAuth on pull/push?**
:A: Make sure you added ``WSGIPassAuthorization true``.

|

:Q: **Git fails on push/pull?**
:A: Make sure you're using a WSGI http server that can handle chunked encoding
    such as ``waitress`` or ``gunicorn``.

|

:Q: **How can I use hooks in Kallithea?**
:A: It's easy if they are Python hooks: just use advanced link in
    hooks section in Admin panel, that works only for Mercurial. If
    you want to use Git hooks, just install th proper one in the repository,
    e.g., create a file `/gitrepo/hooks/pre-receive`. You can also use
    Kallithea-extensions to connect to callback hooks, for both Git
    and Mercurial.

|

:Q: **Kallithea is slow for me, how can I make it faster?**
:A: See the :ref:`performance` section.

|

:Q: **UnicodeDecodeError on Apache mod_wsgi**
:A: Please read: https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/#if-you-get-a-unicodeencodeerror.

|

:Q: **Requests hanging on Windows**
:A: Please try out with disabled Antivirus software, there are some known problems with Eset Antivirus. Make sure
    you have installed the latest Windows patches (especially KB2789397).
