If you add the line

set hidden

to your local vimrc, it will turn this on globally. This allows
you to leave a buffer (such as with ":bnext", ":enew", ":n", etc)
while maintaining your undo/marks, etc. When you return to that
buffer, you retain all those marks and undo-ability. It also
doesn't force you to write the file or abandon the changes (which
it would do otherwise with the default "set nohidden").
