[bug#56783] [PATCH] doc: fix description for extra-content-ahead

[typ22]

From: tiantian <typ22@foxmail.com>

Hello,

After reading other people's patch emails, I was surprised to find
that I can write common messages. Before, I thought I had to follow
the format of commit logs.

Sorry, due to my first time sending a patch, tension and poor English
lead to guix.texi is wrong. I'm so sorry.

The original purpose of this patch is to solve the problem
that log_format can't used, when we don't use an existing file.
log_format must be placed in http block and before using it.
Current nginx-configuration can't meet this requirement.

Honestly, just to solve the problem, adding log-formats field
may be enough. But, I don't think there is only one problem that
log_format can't be used. I think there may be other directives
like log_format can't be used. So, I add a field to place extra content
before server blocks and upstream blocks. It is simple and flexible.

I am a novice, whether using nginx or submitting patches. If I make mistakes,
please correct me, thank you.

Thanks,
tiantian
