Subject: Compare character with EOF using signed comparison because
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/d2520ac7054ad75d60342606bf13c821305d958c?ds=inline;hp=d2520ac7054ad75d60342606bf13c821305d958c

Compare character with EOF using signed comparison because
EOF can be (and is likely) negative.  This showed up on
arm7, which apparently uses unsigned char for char.
