[PATCH] grep: remove unnecessary "what-if-signal?" code

[Paul Eggert]

I pushed the following as an obvious cleanup of code that
I mistakenly introduced to grep in the previous millennium.


* src/main.c (fillbuf): Don't worry about EINTR when closing --
not possible, since we're not catching signals.
