The trap setup for catching the SIGWINCH and SIGALRM signals now looks
like this:
trap 'basta_uln_save=$_; basta.update_status; : "$basta_uln_save"' ALRM WINCH
instead of just
trap basta.update_status ALRM WINCH
I know that this looks like a hack, but since 'update_status' needs no
arguments you could also more simply just write...?
trap 'basta.update_status "$_"' ALRM WINCH
(Not sure whether introducing a global variable and supplementary code
or this hack is "better". Just mentioning it for a possible variant.)
