The HLP-changes to sbase have been a great addition of functionality, but they kind of "polluted" the enmasse() and recurse() prototypes. As this will come in handy in the future, knowing at which "depth" you are inside a recursing function is an important functionality. Instead of having a special HLP-flag passed to enmasse, each sub- function needs to provide it on its own and can calculate results based on the current depth (for instance, 'H' implies 'P' at depth > 0). A special case is recurse(), because it actually depends on the follow-type. A new flag "recurse_follow" brings consistency into what used to be spread across different naming conventions (fflag, HLP_flag, ...). This also fixes numerous bugs with the behaviour of HLP in the tools using it.
