+       * tex-buf.el (TeX-error--find-display-help): Use new fourth
+       argument of `TeX-help-error'.
+       (TeX-warning): Rename mandatory argument to `warning'.  Do not add
+       leading "** " to warning string.
+       (TeX-warning--find-display-help): Use new fourth argument of
+       `TeX-help-error'.
+       (TeX-error-description-faces): New group.
+       (TeX-error-description-error): New face.
+       (TeX-error-description-warning): Ditto.
+       (TeX-error-description-tex-said): Ditto.
+       (TeX-error-description-help): Ditto.
+       (TeX-help-error): Add new `type' argument.  Color help messages
+       using the new faces.
+       (TeX-warning): Preserve point when searching backward.  In some
+       cases this prevents infinite loops in `TeX-parse-all-errors' and
+       fixes wrong detection of context string.
