Again, like argv, the envp is modifiable. That's actually how setenv() and
putenv() works if you modify an existing variable to a value shorter than
what's already there. However, I'll agree this is a very niche use-case, even
more so than modifying what ps(1) shows (though ps can show the environment
too).
