Re: C-c C-c in recover session produces "Args out of range"

[Boris Aronov]

Ooooooops...  [I just thought I removed the .saves-XXXX file.  I did
not, in fact.]  

So indeed the file, to be more precise that what I reported earlier
contains:

=========
/home/aronov/papers/separation/2003-06-05/separability.tex
/home/aronov/papers/separation/2003-06-05/#separability.tex#






=========

(Note the oodles of extra empty lines at the end---I checked that they
really ARE empty.)  On advice of RMS, I re-run the stack trace with
uncompiled function "recover-session-finish" and got:

=============

I patched the file as you suggested and the error went away.  Since
there are no recoverable things in that .saves-XXX file, I cannot say
much beyond that about its functionality.  I will try to test it the
next time I have to use recover-session.  Thanks!
