Minor change in usr/local/bin/burn to improve readability
Fix bug when invoking 'helpinfo -a' or 'print-pid -a'.
Simplified a little code in print-pid
print-pid now exits with same exit status as its child.
Don't let bash execute 'burn', 'cpuburn-m', 'mprime' scripts, as it blocks signals during 'read' and can bring me trouble.
Edit help of 'burn' to mention exit statuses due to signals. print-pid now prints signal name when the exit status seems to be 'terminated from signal'.
Quote the heredoc delimiter in 'runonce' script. This fix display bug when backslash is substituted.
