Subject: 28.0.50; unexpected scrolling after message-kill-to-signature
Date: Tue, 13 Apr 2021 21:23:48 +0100

Since some days ago in recent builds of the master branch,
message-kill-to-signature (C-c C-z) has become a bit incovenient
because, after it deletes the required region (correctly), it recenters
the buffer so that point goes to the top (so that one only sees the
signature, and no the rest of the message above, as if one had invoked
recenter-top-bottom twice). 

It used to be the case that the buffer were not scrolled at all, which i
found much more convenient (typically, my cursor is in the middle of the
message, i C-c C-z, what's below disappears and i keep seeing the same
that was above it).  

Was this an intended change? If so, any way of recovering the previous
behaviour?  (I see a similar (new) behaviour when i delete a region
inside a polymode/poly-org block, but those packages are complicated and
messy enough to keep them aside, at least for now :)

Thanks!

At bottom, every man knows perfectly well that he is a unique being, only
once on this earth; and by no extraordinary chance will such a marvelously
picturesque piece of diversity in unity as he is, ever be put together a
second time. -Friedrich Nietzsche, philosopher (1844-1900)

I'm unable to reproduce this in Emacs 28 -- If I hit `C-c C-z' in a
Message buffer, it just kills the text after point, and does no
recentring.

Is it possibly that you have customisations of the command that issues a
recentring?  Can you reproduce this bug with "emacs -Q"?

Thanks for checking.  I'm closing this bug report, then.
