I don't understand why you mention expect. This program is intended to solve
more complex problems than this one.

It's in the bug log. But it's just a one-liner based on the code lines you
quoted, so it's not really worth searching for it..

That's nice to hear.

These utilities are general purpose and not specificaly intended to obtain
input from the user. In case a script invokes them with this purpose, it is
the responsability of such script to ensure that question prompts are flushed
out before reading from stdin is attempted.
