/*
* Map and abbreviation structures.
*
* The map structure is doubly linked list, sorted by input string and by
* input length within the string. (The latter is necessary so that short
* matches will happen before long matches when the list is searched.)
* Additionally, there is a bitmap which has bits set if there are entries
* starting with the corresponding character. This keeps us from walking
* the list unless it's necessary.
*
* The name and the output fields of a SEQ can be empty, i.e. NULL.
* Only the input field is required.
*
* XXX
* The fast-lookup bits are never turned off -- users don't usually unmap
* things, though, so it's probably not a big deal.
