I am comforable with using history of edited files that is kept in viminfo, the one that sets the limit in the first setting of set viminfo='100,... variable.

After I've started using mutt as email client and using vim as its editor, and that makes multiple temporary files created in /tmp/dir. These are of no interest and spoil the history of :browse old. I am trying to figure out the way of excluding those so they could be skipped or at least wiped in some hook procedure. They all can be easily identified by /tmp/mutt-.* path regex.

Is there some natural/doable way to implement this?

I guess I found a good solution for my use case. -i option allows to specify alternative locoation of viminfo file. So I can specifey vim -i /tmp/blackhole for cases where I do not care of file history. In my case that is specifying

set editor = "vim -i /tmp/idontcare"

in my .muttrc
