So you probably want to be typing something like C-1 M-! at the
correct point in your buffer.

Oops, typo.  Make that: C-u M-!

Well, what is the obvious thing that you do and what happens when you
do it?  From your description it's not clear to me what you're doing.

Maybe you just need to switch to the *Shell Command Output* buffer
and copy the text from there?  This buffer is not shown by default,
when the output of the shell command is short.

See the document on shell-command-on-region to see how to change it:

/----
| If the command generates output, the output may be displayed
| in the echo area or in a buffer.
| If the output is short enough to display in the echo area
| (determined by the variable `max-mini-window-height' if
| `resize-mini-windows' is non-nil), it is shown there.  Otherwise
| it is displayed in the buffer `*Shell Command Output*'.  The output
| is available in that buffer in both cases.
\----

Does this help?

This is a behavioral change not listed in the news.

It explains where the text got to.  Thanks!  Now I have to
set up a macro to pull that text into the current buffer.

This:

C-x + b + "*Shell Comm" + RET + C-h + a + Alt-w + C-x + b + RET + C-y

is a tad unwieldy.  I like the old behavior of splitting the screen
and bringing up the `*Shell Command Output*' buffer.  Much easier.
*sigh*.  Thanks again.

It's been doing it this way for quite some time.  I still use 20.7 and it
performs this heuristic.

Giving it a numeric argument tells it to insert the output in the current
buffer.  M-! inserts it at the point, M-| replaces the region with the
result.

If not a change, then I have inadvertently always had the
mini buffer line limit low enough that I never stumbled into
it before.  Can't tell anymore.  Don't have a 20.x version
access.....

Thanks to all!

The difference is that in versions prior to 21.1, the echo-area could
only display one line, so the split between `display in echo-area' and
`pop up a window' naturally occured at 2 lines.  In emacs 21.x, the
echo-area can expand to show multiple lines, so the echo-area gets used
more often.  [So one way to avoid this behavior is to set
`max-mini-window-height' to 1.]

Of course, if the _reason_ someone wants to get to the output buffer is
to cut the text and insert it into the current buffer, it's much better
to just use a prefix-argument to `shell-command', which does exactly
the right thing...

You can also use the C-u prefix with M-| or M-!...

M-| still runs shell-command-on-region for me.  Maybe this is one of
the distros that mucked up the Alt and Meta keys?  What does C-h k M-|
show you?
