configfile: fix EOF handling
Currently we can end up passing EOF to isspace(), which is in fact libgit's sane_isspace which does: ((sane_ctype[(unsigned char)(x)] & (GIT_SPACE)) != 0) It is very unlikely that EOF cast to "unsigned char" will end up in a character that has the GIT_SPACE bit set, but the standard only requires that EOF be a negative integer, so it could access any value in the sane_ctype array. If it does end up returning true for isspace() then this loop will never terminate, so handle EOF as a special value in the same way as the other loops in this function.
