netrc should be able to ignore some tokens like 'protocol'

Feature or enhancement

Proposal:

netrc._parse() rejects unknown tokens.

So far so good except some tools like git also use netrc files for authentication purposes through git-credential-netrc helper.

The issue is that git-credential-netrc expects a few other tokens like protocol that are currently rejected by netrc._parse()

It would be nice to be able to just ignore those tokens instead of failing the parsing of the netrc file.

I can't tell whether we should just register these exact tokens as "to be ignored", or if it would be better to have a way for netrc users to register the tokens they wish to ignore.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

从 netrc._parse() 入口点开始，检查解析器如何处理 git-credential-netrc 使用的协议令牌。当包含此类令牌的 netrc 能够无错误地完成解析，同时现有的解析行为保持不变时，即可视为完成。
