Rely on [] evaluating empty string as false, non-empty string as true
to eliminate a lot of -z and -n tests.
Thus,
'[ -z "$x" ] && cmd' -> '[ "$x" ] || cmd'
'if [ -z "$x" ]; then; y; fi' -> '[ "$x" ] || y'.
'[ -n "$x" ]' -> '[ "$x" ]'
Use variable default value syntax in a couple of places rather than if
statements. e.g. ': ${_ouranswer:=$_ifs}'.
Suggestions from millert@, aaron@, espie@, miod@ at various times.
