git am -s didn't like your patch: From: Mark Edgar <medgar123@gmail.com> XftFontMatch calls XftDefaultSubstitute which configures various match properties according to the user's configured Xft defaults (xrdb) as well as according to the current display and screen. Most importantly, the screen DPI is computed [1]. Without this, st uses a "default" DPI of 75 [2].
