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.
