(fill-delete-newlines): Call sentence-end as function.
(fill-nobreak-p, canonically-space-region): Likewise.
(fill-nobreak-p): If this break point is at the end of the line,
don't consider the newline which follows as a reason to return t.
a paragraph starter when filling non-comments.
(fill-comment-paragraph): Use comment-search-forward.
Recognize paragraph starters and separators within comments.
Use adaptive-fill-prefix when it works. Don't narrow while doing the fill.
_before_ checking to see if we're hitting the margin.
(fill-region-as-paragraph): Don't fiddle with the undo-list any more:
it's now done by the C primitives. Don't use narrowing.
Reorganize the line-breaking part of the code to simplify the control
flow and make it work in the absence of narrowing.
(fill-region): Don't use narrowing.
Don't add spaces at end of sentences at end of line.
(fill-move-to-break-point): Make sure the result is always greater
than linebeg, so we ensure forward progress.
(fill-region-as-paragraph): Compare to `to' rather than eobp.
(fill-paragraph): Don't rebind fill-paragraph-function.
(fill-delete-prefix): Remove indentation while removing prefix.
(fill-delete-newlines): Obey sentence-end.
(fill-move-to-break-point, fill-newline): New functions extracted
from fill-region-as-paragraph.
(fill-region-as-paragraph): Use them.
Don't fiddle with fill-indent-according-to-mode.
New functions, extracted from fill-region-as-paragraph.
(fill-region-as-paragraph): Use them.
Use an end marker instead of eob.
Ignore whitespace-only fill-prefixes when indenting according to mode.
Simply the loop that searches for spaces backwards.
(fill-indent-according-to-mode): Change default to t.
(fill-context-prefix): Simplify control-flow and use a more
sophisticated merge that unifies both previous checks.
(fill-single-word-nobreak-p, fill-french-nobreak-p): New funs.
(fill-nobreak-predicate): Make it into a defcustom'd hook.
(fill-nobreak-p): New fun.
(fill-region-as-paragraph): Use it.
Handle `fill-indent-according-to-mode' slightly differently.
(fill-individual-paragraphs-prefix): Simplify the control-flow.
(fill-individual-paragraphs-citation): Fix.
rather than using (match-beginning 0) when searching for break point.
Because match-data might have been destroyed by fill-nobreak-predicate
or might never have been setup if the re-search-backward has failed.
