Remove padding when code spans/code link spans are adjacent

[Nemo157]

I used

[`Stream`](futures::stream::Stream)`<Item = `[`io::Result`](std::io::Result)`<`[`Bytes`](bytes::Bytes)`>>`

in some crates documentation which renders as

There is currently a 0.1em padding applied inside all code spans causing the spacing to look weird. It seems like adjacent code spans (including ones wrapped inside <a>) should have the padding suppressed so they render as if they were one code span.

There was a reason for this. I'll check why.

The reason why:

It's not very nice looking on "normal" blocks to not have a bit of padding.

I've got an idea on how to fix. Let's put it to try!

Won't work, CSS is too limited for that. The only solution I see currently would be to be able to detect that code tags are following each others and merging them as one.

Here is how I currently work around this in Syn (without merging code tags):

• https://docs.rs/syn/0.15.40/syn/struct.Generics.html#method.type_params
• https://github.com/dtolnay/syn/blob/0.15.40/src/generics.rs#L76-L82

That's something! 🤣
