Because the next token is EOF and no TRAPs are defined.

Take cron for example. Modifying the SHELL variable would be easy, but
changing all entries is much more work. Or the window manager IceWM. I
can configure the shell that's used to run subprocesses for menu entries,
but modifying all menu entries, and some of them are build by third party
scripts, is expensive.
