Get "Undefined variable: g:signify_detecting" error when I start vim. about vim-signify

[snobb]

Never mind, looks like it's the conflict that was caused by the extension installed multiple times:

$ find .vim/pack/ -type d | grep signify
.vim/pack/<user1>/start/vim-signify
...
.vim/pack/<user2>/start/vim-signify
...

removeing .vim/pack and downloading the extension again solved the issue.

PS: Thank you for the best VCS vim extension out there. :) Great job!
