+    libio: Check remaining buffer size in _IO_wdo_write (bug 31183)
+    
+    The multibyte character needs to fit into the remaining buffer space,
+    not the already-written buffer space.  Without the fix, we were never
+    moving the write pointer from the start of the buffer, always using
+    the single-character fallback buffer.
+    
+    Fixes commit 04b76b5aa8b2d1d19066e42dd1 ("Don't error out writing
+    a multibyte character to an unbuffered stream (bug 17522)").
