[PATCH 6/7] notes-merge: use ssize_t for write_in_full() return value

[Jeff King]

We store the return value of write_in_full() in a long,
though the return is actually an ssize_t. This probably
doesn't matter much in practice (since the buffer size is
alredy an unsigned long), but it might if the size if
between what can be represented in "long" and "unsigned
long", and if your size_t is larger than a "long" (as it is
on 64-bit Windows).
