i18n: check equality of initial indentation between msgid and msgstr

Document generation by runrst in "doc" directory may succeed silently,
even though initial indentation is different between msgid and msgstr:
for example, it may be unexpected or missing indentation.

This patch adds the checker to check equality of initial indentation
between msgid and msgstr.

This checker is categorized as "warning" level, because problem
detected by this is not so serious for usual Mercurial usage.

# An example WSGI script for IIS/isapi-wsgi to export multiple hgweb repos
# Copyright 2010 Sune Foldager <[e-mail]>
#
# This software may be used and distributed according to the terms of the
# GNU General Public License version 2 or any later version.
#
# Requirements:
# - Python 2.6
# - PyWin32 build 214 or newer
# - Mercurial installed from source (python setup.py install)
# - IIS 7
#
# Earlier versions will in general work as well, but the PyWin32 version is
# necessary for win32traceutil to work correctly.
#
#
# Installation and use:
#
# - Download the isapi-wsgi source and run python setup.py install:
#   http://code.google.com/p/isapi-wsgi/
#
# - Run this script (i.e. python hgwebdir_wsgi.py) to get a shim dll. The
#   shim is identical for all scripts, so you can just copy and rename one
#   from an earlier run, if you wish.
#
# - Setup an IIS application where your hgwebdir is to be served from.
#   On 64-bit systems, make sure it's assigned a 32-bit app pool.
#
# - In the application, setup a wildcard script handler mapping of type
#   IsapiModule with the shim dll as its executable. This file MUST reside
#   in the same directory as the shim. Remove all other handlers, if you wish.
#
# - Make sure the ISAPI and CGI restrictions (configured globally on the
#   web server) includes the shim dll, to allow it to run.
#
# - Adjust the configuration variables below to match your needs.
#

# Configuration file location
hgweb_config = r'c:\src\iis\hg\hgweb.config'

# Global settings for IIS path translation
path_strip = 0   # Strip this many path elements off (when using url rewrite)
path_prefix = 1  # This many path elements are prefixes (depends on the
                 # virtual path of the IIS application).

import sys

# Adjust python path if this is not a system-wide install
#sys.path.insert(0, r'c:\path\to\python\lib')

# Enable tracing. Run 'python -m win32traceutil' to debug
if getattr(sys, 'isapidllhandle', None) is not None:
    import win32traceutil

# To serve pages in local charset instead of UTF-8, remove the two lines below
import os
os.environ['HGENCODING'] = 'UTF-8'
