Eg. with foo.el below emacs -Q foo.el M-x end-of-buffer M-x align => Invalid search bound (wrong side of point) In `align-region' it seems `last-point' is established from `b' which is an integer buffer position but that position is invalidated by whitespace deletes before that point (done by `align-regions'). I get some joy from making the marker before changing the buffer, per below. Alternately (untested!) perhaps `b' could be a marker to start with, ready to be the new value of `last-point'. 2010-05-17 Kevin Ryde * align.el (align-region): For `last-point' take marker of b position before align-regions because that function inserts or deletes text before there. In particular fixes "Invalid search bound" when there's two sections in the region and alignment in the first deletes a lot of whitespace. --=-=-= Content-Type: application/emacs-lisp Content-Disposition: attachment; filename=foo.el Content-Transfer-Encoding: quoted-printable (ab . c) (def . ghi) (ab . c) (foo . bar) (foo . bar) --=-=-= Content-Type: text/x-diff Content-Disposition: attachment; filename=align.el.last-point.diff --- align.el.~1.35.~ 2009-03-28 09:41:43.000000000 +1100 +++ align.el 2010-05-16 19:03:40.000000000 +1000 @@ -1502,10 +1502,10 @@ (align-new-section-p last-point b thissep)) (progn + (setq last-point (copy-marker b t)) (align-regions regions align-props rule func) - (setq last-point (copy-marker b t) - regions nil + (setq regions nil align-props nil)) (setq last-point (copy-marker b t))) --=-=-= In GNU Emacs 23.1.1 (i486-pc-linux-gnu, GTK+ Version 2.16.5) of 2009-09-14 on raven, modified by Debian configured using `configure '--build=i486-linux-gnu' '--host=i486-linux-gnu' '--prefix=/usr' '--sharedstatedir=/var/lib' '--libexecdir=/usr/lib' '--localstatedir=/var/lib' '--infodir=/usr/share/info' '--mandir=/usr/share/man' '--with-pop=yes' '--enable-locallisppath=/etc/emacs23:/etc/emacs:/usr/local/share/emacs/23.1/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/23.1/site-lisp:/usr/share/emacs/site-lisp:/usr/share/emacs/23.1/leim' '--with-x=yes' '--with-x-toolkit=gtk' '--with-toolkit-scroll-bars' 'build_alias=i486-linux-gnu' 'host_alias=i486-linux-gnu' 'CFLAGS=-DDEBIAN -g -O2' 'LDFLAGS=-g' 'CPPFLAGS='' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: en_AU value of $XMODIFIERS: nil locale-coding-system: iso-latin-1-unix default-enable-multibyte-characters: t --=-=-=--
