Clear to eol before outputting line in multi-line prompt

Browse source 
If the user has a multi-line prompt, we will emit a clr_eol on every
line except the last (see #7404). Prior to this change we would emit
clr_eol after the line, but in some terminals, if the line extended the
width of the tty, the last character would be deleted. Switch to
emitting clr_eol first; now the last character will not be cut off.

Fixes #8002
