Doesn't happen on 2 systems I tried with the current master branch.
Of course, I don't have your "~/.emacs.d/emacs/lisp/" directory, so
maybe this depends on the actual files in a directory. Does this
happen in the Emacs's lisp/ directory?
Is this in "emacs -Q" on the master branch?
"M-x grep" puts a display property on the null characters, showing
them as ":". So why doesn't it happen in this case, and why there's a
":" _in_addition_ to the null character?
I think that ":" was my typo, it was supposed to come after the line number.
The ^@ are escape-glyphs (which is fine) but weirdly show up only after I C-v. I repro'd on Emacs 30.1 also. The emacs subdir is a symlink to my git-controlled master working tree and the file names there are normal (and it's the precise build I was using at the time).
It could be my config, so I'll dig into this more.
