A few things:

1. the 'exe' should be 'call' in the autocmd, as such:

autocmd! BufReadPre * silent call RecordFileOpen()

(The 'silent' is to prevent seeing the log entry on the screen.)

2. With BufReadPre, you get log entries when using Vim's built-in 'help'

But, maybe that's fine for what you're using it for.

3. I'd guess you probably also want BufNewFile (when calling vim on a nonexistent
file):

au! BufReadPre,BufNewFile * sil call RecordFileOpen()
