Subject: Clear spinner after each cycle
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=0e3a089704531566fe801a6b4426edc1a4c79e8f;p=openbsd

Clear spinner after each cycle

Otherwise we can get left with a piece of the spinner if all firmware
gets updates and don't print a "kept" value.

While here, replace \010 with the ksh supported \b, as suggested by cheloha@
