Mara Bos 540d4743cc Rollup merge of #78603 - petrochenkov:fourdigits, r=matthewjasper ... expand: Tweak a comment in implementation of `macro_rules` The answer to the removed FIXME is that we don't apply mark to the span `sp` just because that span is no longer used. We could apply it, but that would just be unnecessary extra work. The comments in code tell why the span is unused, it's a span of `$var` literally, which is lost for `tt` variables because their tokens are outputted directly, but kept for other variables which are outputted as [groups](https://doc.rust-lang.org/nightly/proc_macro/struct.Group.html) and `sp` is kept as the group's span.
