Use Fnext_property_change to get a quick lower bound for
where `invisible' changes.

(compute_motion, vmotion): Check `invisible' prop
using TEXT_PROP_MEANS_INVISIBLE.

Fix Lisp_Object vs. integer problem.
(width_run_cache_on_off): Let recompute_width_table create the vector.

(character_width, disptab_matches_widthtab, recompute_width_table,
width_run_cache_on_off): New functions.
(compute_motion): Call width_run_cache_on_off.  If this buffer's
width run cache is enabled, consult it to see if we need to
traverse a region character-by-character; store information in the
cache after doing so.  Call find_before_next_newline instead of
writing out an equivalent loop explicitly, to take advantage of
the newline cache.
Doc fixes.

compute_motion, Fcompute_motion, vmotion): Don't use XFASTINT as an lvalue.

vmotion): Use type test macros.

(indented_beyond_p): Likewise.

(Fcompute_motion): Use whatever buffer is current.

prompt.

(Fcompute_motion): Likewise.

Also extracted long doc string to avoid compiler limitations.

Also another doc fix.

(Fcompute_motion): New function.

(compute_motion, vmotion): Use it to treat blank lines specially in selective
display.

were too low by 1.

(vmotion): Take care of invisible newlines.

(Fmove_to_column): After we split a tab, make sure
to set last_known... consistently.
