I found a solution, although I'm not sure why it works.
When you just hit enter getty goes back to the beginning of its loop.
This also happens if you enter a name starting with "-" or consisting of
just spaces. These also causes the output to become garbled.
At the beginning of the loop it calls setttymode(0). If I insert a
sleep(1) before this call, everything works correctly. If I insert the
sleep after that, the output still gets garbled.
Like I said, I don't know why it works, but it does.
I don't think a short delay is unreasonable after entering invalid or no
information. I am going to submit a PR with a patch.
