this actually makes more sense, as to the cmdbuflen size.
len=`echo "0${command} ${swatch_flags} (perl)0" | wc -c`
if [ $len -ge 255 ];then
takes the command, swatch flags, the (perl) added to end, and two byte
buffer (the 0). and if GE 255, then:
either FAIL with err 1 swatch_${i}_flags too long
or set procname = %%LOCALBASE/bin/perl.
this seems to work in all cases.. start/stop/status, one file in
tail-file, several files in tail-file, etc.
