fix a few links

[lqd]

The post-processor didn't linkify the RFC link from last time, so here is the PR I promised.

There was also a couple other links to fix in the RFL page.

I'd rather we figure out the linkifer bug. Or maybe those were disabled because the impl was so crappy, I remember @joshtriplett complaining about it.

[nikomatsakis]

Hmm. There is a linkifier declared:

rust-project-goals/book.toml

Lines 18 to 21 in 3ed26fd

	[preprocessor.goals.linkifiers]
	"RFC #([0-9]+)" = "https://github.com/rust-lang/rfcs/pull/$1"
	"([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)#([0-9]+)" = "https://github.com/$1/$2/issues/$3"
	"#([0-9]+)" = "https://github.com/rust-lang/rust/issues/$1"

I don't get why it's not working...?

#204 was the bug I was thinking of

[compiler-errors]

Doesn't that only parse RFC #3716, not RFC 3716?

[compiler-errors]

I assume it should be RFC #?([0-9]+) if we want to allow both.

it was RFC #3716 in the original text, which causes even more confusion as to why it didn't work

Sure, I will try to find out.

[lqd]

The linkifier is not disabled locally and seems to work, but these links were using the incorrect micro-syntax: the linkifier doesn't trigger on RFC #123 but on [RFC #123].

I've updated the PR to restore and fix the original text.

Thanks @lqd !
