It currently goes one token too far.

Example: line 259 of tests/ui/abi/compatibility.rs:

test_abi_compatible!(fn_fn, fn(), fn(i32) -> i32);

This commit changes the span for the second element from fn(), to fn(), i.e. removes the extraneous comma.

This doesn't affect any tests. I found it while debugging some other code. Not a big deal but an easy fix so I figure it worth doing.

Oof, yeah. Span handling in the parser can be very manual.

Unless there's a good reason to believe that this test is impossible to create

@compiler-errors: the decl_span field has a single meaningful use:

rust/compiler/rustc_resolve/src/late.rs

Line 813 in 7a08f84

let span = ty.span.shrink_to_lo().to(bare_fn.decl_span.shrink_to_lo());

and the hi field (i.e. the part changed by this PR) isn't even used, lol.

So the only way to test this would be with a -Zunpretty=ast-tree test, but that seems like overkill. I suggest we merge as is.

Please note that I have also modified a comment in the updated version.

Talk about serendipity: this incorrect span had no meaningful uses until @spastorino added one in #126758, a PR that came after this one! But now we can see the effect in the changed test output, so that's nice.
