Is this a hack? (action=showpost)

[Jawelin]

I got it installed months ago and with ver 2.2.5 still works perfectly.
Just, when applying some hack to that file, I had to do twice ...
For example, with 'minimum posts' or 'password hack' or whatever else...

Now I would try to mixup better the 'action=="showpost"' section with the othes in reason to write most parts only once.
Did anyone solved this point, already ?

Thanks
