linux中svn配置出错 conf/svnserve.conf:12: Option expected 解决方法

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
