$ cat Makefile
mmm:
echo 111 #;\
echo 222
$ emacs Makefile #shows the second line in comment color,
but when one does M-x compile, we see the second line is indeed executed.

I can reproduce this on current master. That said, is this really a
common use-case?

That way hackers can hide code in the "comments" that will actually get
executed by unsuspecting programmers.
Imagine a malicious code hidden in a copyright notice section,
sent to staff to "just test this."

That's how many security bugs work: non-common use cases.
