+Subject: wall: convert homebrew buffering to open_memstream()
+
+The struct buffer system duplicates a plethora of standard I/O
+functions (including a fork of fputc_careful())
+and adds a lot of complexity ‒ open_memstream() is standard,
+and fits perfectly into this niche
+
+Origin: https://github.com/util-linux/util-linux/commit/27ee6446503af7ec0c2647704ca47ac4de3852ef
