the added benefit of handling multiple string-styles as long as
they are not nested).
Jump to the slow code as soon as a comment starter is found in
a "string_lossage" position. Fixes the case: " /* " /* " */.

Check the comstyle of single-char comment-starters.
Clarify control-flow around the Scomment case.

(Fforward_comment, scan_lists):
Check the comstyle of single-char comment-starters.
(scan_sexps_forward): Don't try to recognize `half comment-enders' if
we're just at the beginning of the comment (f.ex with (*) ... (*)).

regarding the "parent" handle. These just separate out the different

changes will do type checking and enforcement.
* intervals.h (NULL_INTERVAL): Cast to INTERVAL type.
(INT_LISPLIKE): New macro.
(NULL_INTERVAL_P): Use it.
(INTERVAL_HAS_PARENT, INTERVAL_HAS_OBJECT, SET_INTERVAL_PARENT,
SET_INTERVAL_OBJECT, INTERVAL_PARENT, COPY_INTERVAL_PARENT,
GET_INTERVAL_OBJECT, INTERVAL_PARENT_OR_NULL): New macros.
* alloc.c (make_interval, gc_sweep): Use new macros; eliminate all
explicit references to "parent" field of struct interval and
associated unclean type conversions.
* intervals.c (create_root_interval, root_interval, rotate_right,
rotate_left, balance_possible_root_interval, split_interval_right,
split_interval_left, interval_start_pos, find_interval,

reproduce_tree but takes a Lisp_Object for the parent. Declare
with prototype.

object before trying to examine its type.
