Yes, that patch was for highlighting based on foldlevel. I think totally flexible contained highlighting would be difficult to implement, and also to configure. (Maybe a concept of nested highlight groups, (like "H1 B" or "OL > LI" in Cascading Style Sheets) would help). However, for the OP's purpose (and other uses of folding), it would already be helpful if highlighting of folded text could be transparent, so that the original syntax definitions would apply. (You cannot simply achieve this via ":hi clear Folded".) Somewhat related, I have once wished for some uses of folding that (the first) sign contained within a closed fold could be made visible. -- regards, ingo -- You received this message from the "vim_dev" maillist.
