Behavior

When trying to save a *.go file, vim-go throws a big error:

The problem appears to be introduced with this merge: https://github.com/fatih/vim-go/commit/5730b71ea57c3db0972968889a1d098139cb6031 after reverting that the errors stop.

Seeing that error too with my config.

E121: Undefined variable: s:default_list_type_commands
E116: Invalid arguments for function get(s:default_list_type_commands, a:for))
E116: Invalid arguments for function s:listtype(get(s:default_list_type_commands, a:for))
E15: Invalid expression: s:listtype(get(s:default_list_type_commands, a:for))

I am also able to stop the errors by reverting to commit b319ed9753906a0737bfbd5d5e69b443966a8cd8

@hackebrot if you roll back that commit I mentioned the error goes away. it's a good temporary fix.

Thanks for reporting! #1453 should fix it; I don't have time to test it extensively at the moment, need to do some other stuff now. Would appreciate if you could test.
