Subject: [PATCH 2/2] top: cursor repositioning includes line oriented input

A recent patch introduced the ability to recognize the
need to reposition the cursor at suspension or program
end. There remained unmet 1 additional potential need.

This commit extends that ability to embrace line input
so that if a user issues ^Z or ^C while being prompted
the resulting shell output will no longer be embedded.
