/*
* These are def's to help manage local, private flags pine uses
* to maintain it's mapping table (see MSGNO_S def). The local flags
* are actually stored in spare bits in c-client's per-message
* MESSAGECACHE struct. But they're private, you ask. Since the flags
* are tied to the actual message (independent of the mapping), storing
* them in the c-client means we don't have to worry about them during
* sorting and such. See {set,get}_lflags for more on local flags.
*
* MN_HIDE hides messages which are not visible due to Zooming.
* MN_EXLD hides messages which have been filtered away.
* MN_SLCT marks messages which have been Selected.
* MN_SRCH marks messages that are the result of a search
* MN_COLL marks a point in the thread tree where the view has been
* collapsed, hiding the messages below that point
* MN_CHID hides messages which are collapsed out of view
* MN_CHID2 is similar to CHID and is introduced for performance reasons.
* When using the separate-thread-index the toplevel messages are
* MN_COLL and everything else is MN_CHID. However, if we view a
* single thread from there, instead of marking all of those top
* level threads MN_HIDE (or something) we change the semantics
* of the flags. When viewing a single thread we mark the messages
* of the thread with MN_CHID2 for performance reasons.
