If M-x align deletes a lot of whitespace doing its alignment it can get
an "Invalid search bound" error. 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'.

* 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.
