Contextual port normalization refused any port followed by a period, so
common log lines such as "Listening on port: 8080." or
"http://localhost:8080." kept their run-specific port and equivalent
captures compared as changed. Accept a sentence-ending period while
still refusing a period that continues a decimal, version, or host name,
and bump the committed port-normalization version.
