[PATCH 5/7] Don't exit successfully on EPIPE in read_or_die.

["Shawn O. Pearce" <spearce@spearce.org>]

Junio pointed out to me that read() won't return EPIPE like write()
does, so there is no reason for us to exit successfully if we get
an EPIPE error while in read_or_die.

Instead we should just die if we get any error from read() while
in read_or_die as there is no reasonable recovery.
