[sup-talk] Missing the save index option (patch attached)

[Israel Herraiz <israel.herraiz@gmail.com>]

Hi all,

since the last changes to get rid of the save option and to migrate to
the Xapian index, I am really missing the save index option.

Currently, when Sup exits, all the changes to the index are flushed,
and in my case it takes ages because I am a heavy email load user. For
me that is a problem, because my Sup is always open, and I usually
suspend my laptop. From time to time, my laptop won't wake up, and I
am forced to do an unclean reboot. When I open again Sup, all the
changes I did (archiving threads, etc) are lost because the index was
not flushed.

I know that I can use the XAPIAN_FLUSH_THRESHOLD option, but if I use
that option, when the threshold is reached it interrupts me while I am
dealing with my email, and I have to wait some seconds until the index
is flushed. This behavior is very annoying.

I don't know if someone else in this list is also missing the
possibility of flushing the index from Sup. I have done the attached
changes to my Sup, that recovers a sort-of the old save index
option. I am sending to the list just in case the patch is useful for
others too. If there are not strong objections to this change, I
suggest to merge it with Sup.

Cheers,
Israel
