(syms_of_buffer): Doc fix for cache-long-line-scans.

[! SYSVIPC] (main): Fix uses of FD_* macros: fd_set arg is a pointer,
descriptor arg comes first.

(ispell-highlight-spelling-error):
Have just one definition, which decides what to do.

built for.
(display_text_line): Use compute_motion to skip forward to the
left edge of the window when the window is hscrolled; this is

the hscroll is large.

(newline_cache_on_off): New function.
(scan_buffer): New argument END.  Call newline_cache_on_off.  If
this buffer's newline cache is enabled, consult it to see if we

cache after doing so.

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.
