*** Changes to lazy-lock support mode<BR>
The lazy-lock package, one of the two Font Lock support modes, can now fontify
according to the true syntactic context relative to other lines.  You can use
the new variable lazy-lock-defer-contextually to control this feature.  If
non-nil, changes to the buffer will cause subsequent lines in the buffer to be
refontified after lazy-lock-defer-time seconds of idle time.  If nil, then only
the modified lines will be refontified; this is the same as the previous Lazy
Lock mode behaviour and the behaviour of Font Lock mode.
<P>
This feature is useful in modes where strings or comments can span lines.
For example, if a string or comment terminating character is deleted, then if
this feature is enabled subsequent lines in the buffer will be correctly
refontified to reflect their new syntactic context.  Previously, only the line
containing the deleted character would be refontified and you would have to use
the command M-g M-g (font-lock-fontify-block) to refontify some lines.
<P>
As a consequence of this new feature, two other variables have changed:
<P>
Variable `lazy-lock-defer-driven' is renamed `lazy-lock-defer-on-scrolling'.
Variable `lazy-lock-defer-time' can now only be a time, i.e., a number.
Buffer modes for which on-the-fly deferral applies can be specified via the
new variable `lazy-lock-defer-on-the-fly'.
<P>
If you set these variables in your ~/.emacs, then you may have to change those
settings.
