Thomas, I'm a Unix-guy. Apparently you're not. I have to depend on you
to make suggestions as to usable names on Windows, and on where to look
in the source code on how to do it. Please make a suggestion, besides
telling me that "$HOME/...." sounds unix-y. I already know that.

As I see it, having 10 backup project files around is acceptable.
Deleting them when hugin exits succesfully negates part of the "having a
backup". (We of course got into this because "hugin crashes", but a
backup can also protect against: "I had it linedup just fine yesterday,
and now I can't get it to line up correctly! aargh!". For this last
situation, removing the file on succesful exit is not desirable).

Using a "random name" means we can't leave them lying around, because
there might end up lots of them.

On Unix, if you open a file, and then rename (or delete) the file, it
will remain linked to the file you originally opened.

I find "the backup of the first instance of hugin disappears if I open
11 instances of hugin" an acceptable compromise between disk space and
usability. (you'll have up to five backups if you don't open more than
two hugin instances at the same time). A preference setting may be
implemented for this as well. 10 is not a magic number.

the electronics design software "eagle" keeps old versions of your
design around as backups with a number. Every time you save, it moves
the previous versions up one number. This way you have up to 10 backups
of your project should something go wrong.

How about: We save under the "normal" name, with: '.0" attached for the
autosave. When an explicit save comes about, we remove .9, move .8 to
.9, .7 to .8 etc, and then save under the given name. (before naming
your project, the autosave will be in "unnamed.pto.0")


Current patch attached. I didn't manage to get the start-rev right, so I manually removed the other stuff. On the other hand, I hadn't tried "hg view" yet, which I have yet to learn how to use. :-)

Title:
  Backup copy of project.

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  Hugin just crashed on me. Pre 0.7.0 this happened so often that I knew I had to save often, or risk losing my work. 

So far this is the first since I went to 0.7.0. Now 0.8.0 crashed on me.... However I'm most pissed that a pto file got saved to run "nona", but this gets (I think) cleaned up after running nona. So now I'm left with a project file with hours of work missing. 

PLEASE write a backup pto file where I can find it, or mention "this project had unsaved changes when hugin crashed, load the backup file?" when I start it. (then I don't need to know where the backup is stored...).
