In theory, it's religion, but there are a few other places in MojoSetup 
where I've gone over 80 and not yet cleaned it up. GTK+ makes it pretty 
hard to write clean code in 80 columns, with all the GTK_OBJECT_TYPE 
casting macro stuff.

That's probably the correct strategy; I'd have done the same.

> 3) Is the rest of the patch sane?

It appears to be. The file dialog doesn't look like anything I've seen 
in any other GTK+ app, though. I'm not sure why.

Also, it lets you select files (as opposed to just directories).

> 4) How do you prefer contributions?  E-mailed diff's?

Emails to this list, like the patch you sent, are great.

I've committed the patch you sent (svn revision #335)...if you want to 
make further changes (to that work or anything else in gui_gtkplus2.c), 
start from there.

Thanks!
