This occurred when pondering about Forward-inverse search using SyncTeX with the precison of a single word; this "expert knowledge" is however also relevant for any tool that tries to preprocess (La)TeX code, such as latexdiff.

  • @UlrikeFischer: Yes, indeed this adds even more complexity. But still not impossible, just makes the list bigger and... dynamic :-) – krlmlr Jun 14 '12 at 22:08
