[PATCH] git-apply: slightly clean up bitfield usage

[Rene Scharfe <rene.scharfe@lsrfire.ath.cx>]

This patch fixes a sparse warning about inaccurate_eof being a
"dubious one-bit signed bitfield", makes three more binary
variables members of this (now unsigned) bitfield and adds a
short comment to indicate the nature of two ternary variables.
