Installing vim 8 loses janus

[pbdeuchler]

Note: I'm pretty new at vim so there's a good chance this is user error.

I just installed vim 8 via homebrew and made the homebrew binary my default executable. However using that binary seems to bypass all of janus and thus my user customizations. Explicitly loading the new binary with my vimrc file gives me cascading errors:

Looking into this more, it seems like it correctly loads my .vimrc.after file, but fails to load any pathogen plugins (that was probably obvious from the above stacktrace) from my ~/.janus directory.

running vim -V99 seems to also barf pretty hard, i have to kill the vim process to be able to exit

[pbdeuchler]

Just to add to this, installed neovim on a lark and looks like it also fails to load my .vimrc.after as well

[pbdeuchler]

Argh, okay, confirmed it is loading my .vimrc.after however again, none of my pathogen plugins take effect

For what it's worth: I upgrade to vim 8 and never had any issues with janus. Same config

I can confirm, I had the same issue. Downgraded vim to 7.4 and all back to normal
