Doc strings don't specify correctly when the buffer
is erased, in what buffer position the output is
inserted or when the mark is set.

LGTM, but: why do you need to say it's inserted after point, since the buffer is erased anyway?

> +Any other value, excluding nil, means to insert the output
> +in the current buffer after START.

"Any other non-nil value"? I read this wrong on the first read. Doesn't matter much though.

You are right.  I removed that part.

matter much though.
Your wording reads better.  I rewrote following your suggstion.
Thank you.

Doc only fixes should go in emacs-25, I think (unless they document
something that's only in master, but AFAIK shell-command-{on-region}
hasn't been changed...)

Sorry for that.  I assumed fixes to emacs-25 would hardly being accepted 
because the proximity of the release.

There is another wrong sentence in the doc strings for 
shell-command[-on-region]

The output buffer is not deleted: the code killing that buffer was 
commented:

;; It is rude to delete a buffer which the command is not using.
;; Don't kill: there might be useful info in the undo-log.

I am going to push the patch fixing the new issue
(sentence saying that command may delete buffer '*Shell Command Output*')
to the master branch.
