Subject: Discard too short log lines
X-Git-Url: http://git.itanic.dy.fi/?p=log-plotter;a=commitdiff_plain;h=5b5bb6500af4523d153306590d24032552cc17ed

Discard too short log lines

Some times the serial output contains incorrect entries, typically in
the beginning of log acquicition. Discard them so that they don't
clutter the log output.
