Solving a Vim error: -complete used without allowing argumentsError, argumentsline

I’ve been getting these messages at startup since upgrading vim:

$ vim
Error detected while processing [...]/.vim/plugged/tlib_vim/plugin/02tlib.vim:
line   77: E1208: -complete used without allowing argumentsError detected while processing [...]/.vim/plugged/vim-fugitive/plugin/fugitive.vim:
line  470: E1208: -complete used without allowing argumentsline  471: E1208: -complete used without allowing argumentsline  475: E1208: -complete used without allowing argumentsline  478: E1208: -complete used without allowing arguments
Press ENTER or type command to continue

I guess Vim broke their interface and all plugin authors had to react. Upgrading 02tlib.vim and vim-fugitive were enough to fix it for me.

Here are some relevant links:
