[PATCH] Avoid printing LF in progs/tabs.c

[James Clarke]

Rather than terminating the string printed to the terminal with LF, we
can terminate it with CR. This avoids having a blank line appear in the
terminal after calling tabs.

I don't know why this was using LF, but the FreeBSD equivalent uses CR (e.g.
https://github.com/freebsd/freebsd/blob/330cbf8/usr.bin/tabs/tabs.c#L181).
Tested on the Linux console and GNOME Terminal.
