Mercurial:启用git subrepo

最近默认情况下禁用了此行为。该消息提示您查看帮助页面,但没有帮助,至少对我没有帮助。

 "subrepos"
    ----------

    This section contains options that control the behavior of the
    subrepositories feature. See also 'hg help subrepos'.

    Security note: auditing in Mercurial is known to be insufficient to
    prevent clone-time code execution with carefully constructed Git subrepos.
    It is unknown if a similar detect is present in Subversion subrepos. Both
    Git and Subversion subrepos are disabled by default out of security
    concerns. These subrepo types can be enabled using the respective options
    below.

    "allowed"
        Whether subrepositories are allowed in the working directory.

        When false, commands involving subrepositories (like 'hg update') will
        fail for all subrepository types. (default: true)

    "hg:allowed"
        Whether Mercurial subrepositories are allowed in the working
        directory. This option only has an effect if "subrepos.allowed" is
        true. (default: true)

    "git:allowed"
        Whether Git subrepositories are allowed in the working directory. This
        option only has an effect if "subrepos.allowed" is true.

        See the security note above before enabling Git subrepos. (default:
        false)

    "svn:allowed"
        Whether Subversion subrepositories are allowed in the working
        directory. This option only has an effect if "subrepos.allowed" is
        true.

        See the security note above before enabling Subversion subrepos.
        (default: false)

我认为它在项目的hgrc中添加了以下内容:

[subrepos]
git:allowed

但它给出了一个解析错误。有人知道正确的格式吗?还有,为什么他们决定禁用这个?每次我签出此项目时,我都必须进行此更改?
