[hackers] [slstatus][PATCH] fflush(stdout) to print line by line if stdout is not a tty

From: Josuah Demangeon <mail_AT_josuah.net>
Date: Tue, 8 May 2018 15:13:56 +0200

To reproduce the issue:
        $ slstatus -s | tee

then it would print only when the stdout buffer is full, by block
of multiple lines.

fflush() makes sure the line is printed at every loop iteration
