Subject: fgets() doesn't call fsync() before getting input

I'm writing a program that prints a dialogue to the screen and then asks
for input. In musl, the dialogue does not show before fgets() is called,
however in glibc it does. That causes a blank prompt and also some
confusion. Attached is a minimal example and a log.
