I made a one-file edit version that essentially does the same:
user option to choose postbit style;
caching of templates; (in more places than this hack does, too

)
No need for phrases, template modifications, or 9 (!!) file edits for such a very small but handy hack
In case anyone's interested (if only to see how I did this using
only one file edit while maintaining caching-ness everywhere):
