经常有新手配置基于svnserve的subversion服务器后，

在客户端访问subversion版本库时出现这个错误：

svnserve.conf:12: Option expected

为什么会出现这个错误呢，就是因为subversion读取配置文件svnserve.conf时，无法识别有前置空格的配置文件，如

### This file controls the configuration of the svnserve daemon, if you

### use it to allow access to this repository. (If you only allow

### access through http: and/or file: URLs, then this file is

### irrelevant.)

### Visit http://subversion.tigris.org/ for more information.

[general]

### These options control access to the repository for unauthenticated

### and authenticated users. Valid values are "write", "read",

### and "none". The sample settings below are the defaults.

anon-access = read

auth-access = write

像上面的配置文件中，anon-access是顶行的，没问题，而auth-access就存在前置空格，会导致这个错误。

要避免出现这个错误，应该在去掉这些行前的#时，也要顺手去掉前面的空格.
