Larsi, I think you misunderstand the issue.  My understanding is that this is a feature request: recover-session should recover your entire session after a crash, which it doesn't do, and never has done.

Reopening; obviously, feel free to reclose if I am mistaken (and / or there really is such functionality in Emacs24 now.  Cursory review of the bzr head suggests that there isn't).

I'm unable to reproduce this bug in Emacs 24.  If I have a ~/.saves-*
file, where some of the files are deleted, and some are not, `M-x
recover-session' correctly recovers the non-deleted files.

So either this bug has been fixed by now, or there's something in your
setup I'm now able to reproduce.

Thanks.

I set up a public Darcs repo at
http://porkmail.org/elisp/recover-buffers

Darcs isn't invasive; you don't actually need Darcs to download it.  In
fact you can just browse the code by visiting that URL.

This piggybacks on recover-session, and then just redefines the C-c C-c
keybinding to run recover-buffers-finish instead of
recover-session-finish.  It does call recover-session-finish from inside
recover-buffers-finish, but then proceeds to visit all files from the
auto-save file.

The recover-buffers-skip-list feature probably isn't very useful; my
vague recollection is that my previous version had this feature because
recovering remote Tramp files used to be something I didn't want to
attempt, but these days Tramp is well-supported and I haven't come up
with any other scenario where I would actually still want this.  So
perhaps it should just be obsoleted.

Hope this is useful for y'all,
