I originally created this PR to address c-bata#266, but it looks like this fork already had a fix, which was for c-bata#228.
There was an additional bug, however - the file descriptor was being closed prior to restoring the terminal parameters. I assume that meant that the restore itself did nothing.
This also fixes a nearby code error that's unlikely to cause any actual issues.
I also addressed a staticcheck lint issue.
