emacs -Q
C-x b foo
foo ; Insert something.
M-: (set-buffer-modified-p nil) RET
C-x C-s ; No file is written.

It's easy to change that flag for several buffers
with `Buffer-menu-not-modified' or
`ibuffer-do-toggle-modified'.  Then, if you plan to save those
buffers and if they have buffer-file-name nil, then you
are not offered to save them.

Please don't, at least not unconditionally.  I use this feature all
the time, e.g. when composing email messages.

I don't actually understand why this would be a problem: the user
explicitly wanted to reset the modified status of a buffer, why should
Emacs second-guess what the user meant?  But if there are some use
cases where you find this annoying (please describe them), let's make
this an optional behavior, off by default.

Thanks.

No i don't have in mind cases where i have being annoying but that.
Setting modified flag nil followed to trying to save the buffer
sounds like the user don't want to save the buffer.
I think we can close this bug report.  Thanks.
