Subject: bug#33669: 26.1; Buffer-menu-mode bad UX
Date: Sat, 8 Dec 2018 10:06:48 +0800

When Buffer-menu-execute asks

	Buffer foo modified; kill anyway? (yes or no)

and the reply is no,
that line is removed anyway, deceiving the user
by making the buffer menu incorrect.

The user will promptly seek out such buffers — but they disappeared,
giving the distressing wrong impression that they were killed anyway.

Better keep the buffer menu accurate and show a helpful message like

	7 buffers killed, 1 modified buffer kept

to maintain harmony.

		Peace
