*: more minor cleanups

No need for fflush(stderr) when it's already unbuffered by default.

According to setvbuf(3):

       Normally all files are block buffered.  If a stream refers
       to a terminal (as stdout normally does), it is line
       buffered.  The standard error stream stderr is always
       unbuffered by default.
