algebra.c
Log Message:
Reevaluated the use of (v)snprintf.
On Windows, as on Linux, the size argument is the size of the buffer
to which is printed. The difference between Linux and Windows is that
on Linux if the data doesn't fit, the buffer is still NUL-terminated
(and truncated, obviously), but on Windows the data is truncated but
not NUL-terminated.
The upshot of this is that we can use the correctly-sized buffers, but
we must make sure that truncated buffers are properly NUL-terminated.
