Pasting multi-line input eats comment

[lgoettgens]

We experience this in Oscar.jl (cf. oscar-system/Oscar.jl#4402 (comment))

Try pasting the full code block into the REPL:

julia> x = 1
       # hello
1

If you paste this in 1.11 it looks exactly like here, in 1.12-nightly (08d3c70) and nightly (f6e2b98) it changes to:

julia> x = 1
1

It will also ignore all code following a comment (outside of arrays/tuples/blocks), pasting this

julia> x = 1
       #hello
       y = 2

will just print:

julia> x = 1
1

and y is not assigned.

For 1.11 and 1.10 it prints:

julia> x = 1
       #hello
1

But y is also ignored.
