default-frame-top-level: redisplay panes only when command invoked
default-frame-top-level: redisplay panes only when command invoked

Problem is illustrated in issue #710. In essence even after command
abortion panes got redisplayed. Fixes #710.

Moreover we refactor this loop for code to better reflect intention –
we print prompt and add fresh-lines for the interactor pane. In
principle frame-query-io may be NIL - then command is read from the
event loop. Unnecessary fresh-line is removed before executing the
command.

frame-query-io is fixed for CLIM II conformance.
