Use some semantically more correct buffer operations

When writing into the buffer write to free() bytes starting
at getend(), instead of buffersize_max bytes at get()
-> get() is a read pointer.

This makes no difference in practice though, as we reset
the buffer before the call, so start = end = 0.
