Quoted material manipulation commands

[Russ Allbery <rra@stanford.edu>]

A couple of other things noticed when upgrading to No Gnus....

C-c C-z now trims one fewer blank line.  This is driving me nuts, as it's
destroying my finger memory.  Is there a way to get back to the previous
behavior, or do I need to revert back to my own private implementation of
that feature?

M-RET doesn't appear to reformat the new paragraph any more.  Did I break
something, or was that feature removed?

Also, it no longer correctly handles inserting the whitespace for quoted
text in the form:

>[space][tab]some text some more text
>[space][tab]some text some more text

If I move into the middle of such a paragraph and press M-RET, the first
line of the newly created paragraph after the point starts with just > and
a space, no tab, and the paragraph isn't refilled.

This makes it really difficult to deal with the messages of one of my
regular correspondants.

Thanks in advance for any help!
