[PATCH] Support command line options in svn_apply_autoprops.py

[Wei-Yin Chen]

Hi,

This patch makes trunk/contrib/client-side/svn_apply_autoprops.py take
command line options.
The usage would be:
svn_apply_autoprops.py [-c config_file] [paths to process...]

The -c option specifies the configuration file name, and it overrides
the setting in environment variable SVN_CONFIG_FILENAME.
The rest of the command line arguments are treated as paths to process.

[[[
Make svn_apply_autoprops.py take command line options.
Option -c for svn configuration filename, and the rest for paths to process.
]]]

Regards,
Wei-Yin
