Before this commit, we would jump to the first column after receiving
the '\n' line feed character. This is not the correct behavior, as it
should only move the cursor now. Translating the typed Return key into
the correct CR LF ("\r\n") is the TTY's job, which was fixed in #7184.
Fixes #6820
Fixes #6960
