Don't mark books acquired during acquirement statistics as "seen".

This _could_ be useful for the question "Which books can I expect to have
seen after N acquirements?"

However, when running the acquirement statistics I prefer a slightly
different question: "What are the chances of getting a certain book in
this precise situation?"

Don't know which of the two is the "correct" one, but I think it is annoying
if I have to recreate a character for my book acquirement statistics just
because the old one already "saw" all interesting spells, thus heavily
skewing the results.
