With the benefit of hindsight, the above isn't quite correct since the
printed value will retain any leading whitespace, so it s/b ...

if [[ -z "$OUTPWS" ]]; then
 OUTPWS=`awk -F'=' '/^default(-push)?/{sub(/^\t */,'',$NF);print
$NF}' .hg/hgrc || $FILTER`
fi

Note the additional use of sub() to strip leading whitespace from the
path before printing it.
