Remove `bf' and `it' from `bold' and `italic' (they were wrong and

Don't highlight `textmd', `texttt' and `textrm' with bold-italic.
(latex-skeleton-end-hook): New function.
(latex-mode): Use it.
(tex-start-tex-marker): Remove.
(tex-send-tex-command): Don't set tex-start-tex-marker.
(tex-error-parse-syntax-table): New var.

Ignore tex-start-tex-marker. Don't bother with marker-position.

(isearch-mode): Set `minibuffer-message-timeout' to nil, after
stashing away its original value.
(isearch-edit-string): Temporarily restore `minibuffer-message-timeout'
in the recursive edit.

(refill-mode): Add `refill-pre-command-function' to `pre-command-hook'.
Initialize/cleanup `refill-ignorable-overlay'.
(refill-post-command-function): Don't reset refill-doit in the case
where a self-insertion command doesn't case a refill. Use
`refill-fill-paragraph-at', getting position from `refill-doit'.
(refill-after-change-function): Set `refill-doit' to END.
(refill-fill-paragraph-at): New function, mostly from old
refill-fill-paragraph. Use `refill-ignorable-overlay' to fill only the
paragraph's tail if possible. Update `refill-ignorable-overlay'. Don't
leave point inside the fill-prefix.
(refill-fill-paragraph): Use `refill-fill-paragraph-at'.
