It looks like argv[0] gets reset. Plus I don't think every shell's built-in
"exec" supports that -a flag. I don't see it mentioned in the POSIX man
page for exec -
http://pubs.opengroup.org/onlinepubs/009604599/utilities/exec.html - nor do
I see anything about it on the dash man page -
https://linux.die.net/man/1/dash, I suspect that's specific to bash.
