Subject: Avoid the blinkings.
X-Git-Url: https://www.fleuret.org/cgi-bin/gitweb/gitweb.cgi?p=selector.git;a=commitdiff_plain;h=2cfbebb3bfb34779588bdfbce7b56ede149610cb

Avoid the blinkings.

The update now uses clrtoeol() and clrtobot() instead of clear() so
that lines are cleared before being re-displayed, without a global
blink. Added the ^L key to refresh the screen globally.
