Is there somewhere in the doc.s where the help file syntax is described in detail? In particular, I know that help files delivered with Vim have tags that include non-alphanumeric/non-word chars, but I cannot create hyper links with anything but \w chars. It will create the tag in the "tags" file which looks like it should work, but I get an error saying "cstag: tag not found". I've also been peering at the syntax/help.vim file, and it looks like there's more stuff to know about than ** and ||
