[dev] [st] Refactoring Patch from hackers list

[Gary Allen Vollink]

There was a fairly sizable patch sent into the [hackers] list (not by me)

https://lists.suckless.org/hackers/1709/15554.html

I'm wondering if there is a plan to put this into the repository, or
if it only exists on-list.

Thank you,
Gary Allen
