reindent-then-newline-and-indent has changed its behavior

[Klaus Zeitler]

Symptoms:

The behavior of reindent-then-newline-and-indent has changed in CVS emacs.
Lets say I have in my buffer (_ denotes a blank)

--- snip ---
____line1;
____line2;
____line3;
--- snip ---

When I try reindent-then-newline-and-indent e.g. at the beginning of line2
(or anywhere upto the first non-blank character), the buffer contents change
to:

--- snip ---
____line1;
____
____line2;
____line3;
--- snip ---

i.e. the line that got inserted contains unnecessary whitespace. This didn't
happen in 21.3.
