so we can write a limited amount when using this for TOC and tooltip output. This should solve the problem with slowness that Kornel noticed, which was caused by our trying to write an entire plaintext bibliography every time we updated the TOC. We did that because he had a bibliography inside a branch, and we use plaintext for creating the tooltip that goes with the branch list. Other related bugs were fixed along the way. E.g., it turns out that, if someone had an InsetInclude inside a branch, then we would have been writing a *plaintext file* for that inset every time we updated the TOC. I wonder if some of the other reports of slowness we have received might be due to this kind of issue?
