X-Bullshit: agile TOR over ActivityPub out-scaling configuration solution 

When given the -o flag syscall(1) prints the buffer with an appended
newline, making interactive usage misleading and scripting quite
awkward.

I propose removing the newline.

The only program using syscall(1) in the base system is wloc(1), which
works fine after the patch.  However, it's likely that people have
worked around this in their own scripts so the patch may break them.
