color: evaluate labels at write time
Previously, we stored 2-tuples of text and label in a list and then
evaluated the labels when the buffer was popped. After this patch,
we evaluate the labels at write time and do a simple join when the
buffer is popped.
This patch appears to have no impact on performance, despite creating
fewer 2-tuples and having fewer strings hanging around in memory.
