Org agenda width is one char-column too short

[Tory S. Anderson]

As seen in the linked image, my agenda width is a single char too short so it 
clips the last : of the tags. I always use truncate-lines-mode, so this is a 
minor inconvenience but might be something easily fixed for new users? I think 
it has always done this for me.

Here are my configurations for agenda in Straight; if I'm not mistaken, there 
is nothing here that should effect things. Everything else is still at the 
default. I only got to thinking about this because agenda does such an 
admirable job of fitting to screens (something not easy in many emacs 
situations).
