[PATCH 4/8] gpg-interface: fix const-correctness of "eol" pointer




From: Jeff King <peff@xxxxxxxx>

We accidentally shed the "const" of our buffer by passing it
through memchr. Let's fix that, and while we're at it, move
our variable declaration inside the loop, which is the only
place that uses it.
