I concur with you Erik, character classes are only proven to work
with/in perl 5 across all platforms. I suggest that the need to parse
whitespace can be eliminated entirely by using awk(1) with a
field-delimiter of '=' thus realizing a simpler solution all together,
viz ...

if [[ -z "$OUTPWS" ]]; then
    OUTPWS=`awk -F'=' '/^default(-push)/{print $NF}' .hg/hgrc ||
$FILTER`
fi
