Read the NEWS file (probably with C-h N) for changes, and what to do
about them.  In the current CVS, I have found the following info
which might not necessarily apply to your case since your Emacs is so
very much older (so you probably want to read up on this in your NEWS
file):

*** There is a new lazy highlighting feature in incremental search.

Lazy highlighting is switched on/off by customizing variable
`isearch-lazy-highlight'.  When active, all matches for the current
search string are highlighted.  The current match is highlighted as
before using face `isearch' or `region'.  All other matches are
highlighted using face `isearch-lazy-highlight-face' which defaults to
`secondary-selection'.

The extra highlighting makes it easier to anticipate where the cursor
will end up each time you press C-s or C-r to repeat a pending search.
Highlighting of these additional matches happens in a deferred fashion
using "idle timers," so the cycles needed do not rob isearch of its
usual snappy response.

If `isearch-lazy-highlight-cleanup' is set to t, highlights for
matches are automatically cleared when you end the search.  If it is
set to nil, you can remove the highlights manually with `M-x
isearch-lazy-highlight-cleanup'.

I have a buffer in text-mode that I'd like to align using align.el.
Here are the contents:

    max 4096 cs  70 ap_mp  9 t  55% np 63 ap 63
    max 6291.456 cs  70 ap_mp  9 t  55% np 63 ap 63
    max 8192 cs  70 ap_mp  9 t  55% np 63 ap 63

I'd like to align the fields to the following:

    max 4096     cs  70 ap_mp  9 t  55% np 63 ap 63
    max 6291.456 cs  70 ap_mp  9 t  55% np 63 ap 63
    max 8192     cs  70 ap_mp  9 t  55% np 63 ap 63

Anyone have a good recipe for this?

BTW, I'm using the align.el that comes with Emacs 21.

Which is a reason to avoid making this overly complex.  If you're
going to do something that amounts to package management, then use a
package manager.  All that's needed here is the list of things that
got installed via "make install" so that it may easily be uninstalled
later.

Halloechen!

Just deleted my GNU Emacs 20 and installed
GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

I'm a console terminal user.  I mostly use it
in the XTerm ("Konsole 1.0.1 (KDE 2.1.2)"), but also in the
ordinary text mode terminal.

Two major problems:

1. My terminals use latin-9 (German environment).  My
   .emacs contains

(codepage-setup "850")
(prefer-coding-system 'cp850-dos)
(prefer-coding-system 'iso-latin-1)
; (set-language-environment "Latin-9")
 
(if (eq window-system nil) (set-terminal-coding-system 'latin-1))
(if (eq window-system nil) (set-keyboard-coding-system 'latin-1))

   But when I change this to "latin-9" all characters
   (even thost that are common in latin-1 and -9)
   turn into "?".  What am I doing wrong?

2. In the xterm, my keyboard layout must be latin-1
   apparently.  On the tty console this is wrong and
   should be cp850 instead.  How can I create
   .emacs code that can handle both?

Thank you!

Tschoe,
Torsten.
