The default value of 'viminfo' for vim running on Unix is
'100,<50,s10,h
For vi, it is empty. (See ":help 'viminfo'".)
When vim is running as vi, with only vi features enabled, it is
running in compatible mode. When vim is running with vim features
enabled, it is running in nocompatible mode. (See ":help
'compatible'".)
Note the last sentences in ":help -u":
Using the "-u" argument has the side effect that the
'compatible' option will be on by default. This can have
unexpected effects.
You appear to have a ~/.viminfo file, or a system vimrc file (such
as /etc/vimrc) that sets 'nocompatible'. (Fedora has a /etc/vimrc
that does that.) That is causing this command,
vim -i tmpinfo
to start vim in nocompatible mode, which means that 'viminfo' will
be initialized to
'100,<50,s10,h
When run using this command,
vim -u tmprc -i tmpinfo
vim starts in compatible mode, which means that 'viminfo' will be
initialized to be empty.
I think that explains what you're seeing, which is all expected and
not a bug.
Regards,
Gary
