Booktest failures on julia nightly

[lgoettgens]

e.g. in the scheduled job from this morning here
I have seen the same failures in some PRs as well, e.g. in https://github.com/oscar-system/Oscar.jl/actions/runs/12311840722/job/34362745516#step:10:2229.

The failures happen in cornerstones/polyhedral-geometry and cornerstones/algebraic-geometry.

The issue is that multi-line input with comments is partially broken in the latest nightly versions (only when entering line-by-line, not when pasting). For example try entering something like this:

julia> function bla()
       a=1
       b=2 #a comment
ERROR: ParseError:
# Error @ REPL[2]:3:4
a=1
b=2 #a comment
#  └ ── Expected `end`
Stacktrace:
 [1] top-level scope
   @ REPL:1

In previous julia versions the error only appears after entering the second empty line.
