Not sure, written a while ago, probably when the pattern contains many ports they are separated by "--" and I was not interested in the separation.

Here it is without, perhaps this is better:
port -q rdeps dependentof:zlib | sed -e 's/  /\.\./g' -e 's/^\.\./  /g' -e 's/\.\./\. /g' -e 's/\. \([^\.]\)/\| \1/g'
