Ignore some files when using viminfo+=%

Question

I use in my vimrc the following option:

set viminfo+=%

This allows vim to open the last edited files if you don't pass any arguments to vim.

Is there a way to ignore some files? I want to disable the opening of files like COMMIT_EDITMSG, for example.

:help viminfo-% gives you some hints on how to achieve this:

Quickfix ('buftype'), unlisted ('buflisted'), unnamed and buffers on removable media (|viminfo-r|) are not saved.

I would simply make those files unlisted; as Vim is invoked from the version control system for the commit message, and usually no other files are edited within that session, the buffer listing (:ls) and naviation (:bnext) isn't particularly important there, anyway.

For COMMIT_EDITMSG, you can hook into the existing filetype detection:

autocmd FileType gitcommit setlocal nobuflisted

or set up your own pattern(s):

autocmd BufNewFile,BufRead COMMIT_EDITMSG setlocal nobuflisted
