Re: spotting empty continuation lines

Philip suggested,

|       oSM=$SHELLMETAS SHELLMETAS
|       :0 hcw
|       | egrep -q '^[  ]+$'
|       SHELLMETAS=$oSM
|       :0 a
|       { LOG = "Header contained empty continuation line$NL" }

And that does work.  So at least the temp file and the rm call to get rid of
it are unnecessary.  Thank you.
