ui fix: don't clear to end of screen.

* pw.c (clrline): use the [K sequence rather than
the [J sequence so that we only clear this line, not to the
rest of the screen. Clearing the rest of the screen trashes
any scroll-protected status lines the user may have set up.
Vim respects this, for instance.  I have a setup like that now
and noticed the issue that when I run pw, my status stuff
disappears.
